Sitting is getting steadier. Between 4 and 7 months, babies learn to sit first with support and then without it, often leaning forward on both arms in a pose sometimes called the tripod. [3] By 6 months, many babies lean on their hands to hold themselves up while sitting. [1]
By 9 months, most babies sit without support and move things from one hand to the other. [2] So if your baby still topples after a few seconds, that is within the normal range for 7 months. A few minutes of floor practice helps: hold your baby up in sitting or support their back with pillows while they learn to balance. [3]
Something big is happening in your baby's head. Babies this age are starting to learn that things still exist after they leave view, a concept called object permanence. [5] By 9 months, most babies look for a spoon or toy that drops out of sight. [2] Peekaboo is more than a game now. The AAP recommends it as a direct way to help your baby practice this idea. [5]
The same discovery has an emotional side. Once your baby understands that you keep existing when you walk away, they may start to protest when you do. The AAP describes this as the start of separation anxiety, and it often arrives together with new wariness of strangers. [6] The NHS notes that separation anxiety is common between 6 months and 3 years and is a normal part of development. [7] It means your baby is attached to you. It does not mean something went wrong.
Listen for consonants. The babbling that began around 4 months grows into longer chains that borrow the rhythms of your language. [4] By 9 months, many babies make repeated sounds like mamamama and bababababa. [2] You can keep the conversation going: taking turns making sounds with you is a 6 month milestone, and your baby is likely getting better at it every week. [1]
The CDC recommendation for infants 4 to 12 months is 12 to 16 hours of sleep per 24 hours, naps included. [8] Within that total, patterns differ. The NHS notes that some babies sleep in long stretches, others in short bursts, and that your baby's pattern is unlikely to match any other baby you know. [9]
Night feedings often fade around now. NHS guidance says that for some babies aged 6 months to a year, night feeds are no longer necessary, and some sleep around 15 hours a day with most of it coming at night. [9] If your baby still wakes to eat at 7 months, that is not a failure. Teething discomfort or hunger can still wake babies at this age, the range is wide, and the trend over weeks matters more than any single night. [9]
Safe sleep rules still apply at 7 months. Use a firm, flat sleep surface and keep soft objects and loose bedding out of the sleep area. The AAP notes that pillows, quilts and comforters raise the risk of suffocation. [10]

Open the week calculatorMilk still does most of the nutritional work. The NHS notes that babies at this stage still get most of their energy and nutrients from breast milk or infant formula. [12] The AAP adds that within a few months of starting solids, the daily diet should include a variety of foods: breast milk, formula or both, along with foods such as meats, cereal, vegetables and fruits. [11] Whichever milk path your family is on, the plan works.
Meals are taking shape. NHS guidance says that from about 7 months, your baby will gradually move toward eating 3 meals a day in addition to their usual milk feeds, with textures progressing from smooth purees toward mashed and lumpy food. [12]
Finger foods can start once your baby can sit up and bring hands or other objects to the mouth. The AAP notes that finger foods help babies learn to feed themselves. [11] Think soft, small, and easy to squish between your fingers.
Choking safety comes first. The CDC advises cutting round foods such as grapes, berries and cherries into small pieces, and lists hot dogs, meat sticks and sausages among common choking hazards for young children. [13]
One supplement question is worth settling this month. The CDC states that children younger than 12 months need 400 IU of vitamin D each day. Breast milk usually does not provide enough, so babies who are breastfed or partially breastfed need a daily supplement. Babies who drink 32 ounces or more of fortified infant formula a day do not need one. [14] Both feeding paths are fine. The vitamin plan just differs.
Most of what you notice at 7 months is normal variation. A few signs deserve a call, so you never have to wonder.
Development: if your baby is not meeting the milestones on the 6 month checklist, for example not rolling from tummy to back or not leaning on hands while sitting, or has lost skills they once had, the CDC advises talking with your child's doctor and asking about developmental screening. [1]
Fever: a temperature that rises above 104 F (40 C) repeatedly, at any age, is a reason to call your pediatrician. So is a fever that lasts more than 24 hours in a child younger than 2, or any fever that comes with a seizure. [15]
Acting sick: the AAP also advises calling if your child still acts sick once the fever is brought down, or seems to be getting worse. [15]
Dehydration: fewer than six wet diapers a day and a parched, dry mouth can signal dehydration in an infant. Fewer tears when crying and a sunken soft spot on the head are other signs. The AAP advises notifying the pediatrician immediately if any of these develop. [16]

Month 8 builds on everything above. By 9 months, most babies get to a sitting position by themselves and use their fingers to rake food closer. Many react when you leave the room and lift their arms up to be picked up. [2]
The clingy stretch has an exit. Separation anxiety usually peaks between 10 and 18 months and then fades during the last half of the second year. [6] Meeting it with calm goodbyes now is not spoiling your baby. It is how trust gets built.
Feeding keeps moving too. Over the next two months your baby heads toward 3 meals a day alongside milk feeds, and self-feeding skills grow with every messy tray. [12]
Milestone checklists bracket this age rather than pin it. By 6 months, many babies roll from tummy to back, lean on their hands while sitting, and take turns making sounds with you. [1] By 9 months, most sit without support and look for objects that drop out of sight. [2] A 7 month old is usually somewhere in between, and the normal spread is wide.
CDC guidance for infants 4 to 12 months is 12 to 16 hours of sleep per 24 hours, naps included. [8] Patterns vary widely. The NHS notes that some babies aged 6 months to a year sleep around 15 hours a day, most of it at night, and night feeds may no longer be necessary. [9]
Yes. Separation anxiety is common between 6 months and 3 years and is a normal part of development. [7] The AAP describes it as evidence of a healthy relationship with you. It usually peaks between 10 and 18 months and then fades. [6]
