Your baby still doesn’t need any other food besides your breastmilk or formula. Know that what they are getting is all they need at this stage.
The recommended formula amount from 5 days to 3 months is 2.5 ounces per pound of body weight, per day. From 3 to 6 months, this amount may decrease slightly. Remember to never try to force your baby to finish a bottle. Watch for cues that he or she is full and throw away whatever formula remains if you are formula feeding.
Supervised tummy time every day is important and will help them to practice and perfect their rolling skills. If your baby is starting to show signs of wanting to roll over, it is time to stop swaddling. Rolling over while in a swaddle, especially with their arms restrained, is dangerous. Continue to keep loose blankets out of the crib and use blanket sleepers or footed pajamas for sleep. Safe sleep recommendations are for the first year of your baby’s life.
If you have been feeding or rocking your baby until they go to sleep, you might find this becomes an issue around 3 months of age. Babies need to learn to go to sleep on their own by self-soothing themselves to sleep. Try laying them in their crib when they are drowsy but not quite asleep. During the night, babies often only slightly wake up and will go back to sleep relatively easily after being fed.
If you are breastfeeding at night, you may find that sitting up in your bed and feeding is the most comfortable option. Just remember to not sleep with the baby in your bed. Positioning their crib or bassinet next to yours will be the safest option for your little one.
If you are bottle feeding, having the baby sleep next to you also makes it easier for feedings to be shared between you and your partner. Try having formula pre-made and ready to go in the refrigerator, as it will also help make those overnight feedings easier.
Behavior and development
Some babies might still be spitting up milk at 12 weeks due to reflux. The sphincter, a circular muscle at the top of a baby’s stomach, can be relaxed which allows the contents of their stomach to easily flow up their esophagus food pipe and into their mouth. Unless your baby is failing to gain weight or there are other feeding problems, there is no reason to be concerned. For most babies, reflux improves with time and stomach maturity.
Sometimes, however, it can be very hard to tolerate a baby’s crying, especially when it has gone on a long time and nothing seems to help. Be prepared to have some days which are more challenging than others and ask for help. Let your partner know that you are struggling, especially if you find yourself getting frustrated, overwhelmed, or angry.
Remember never to shake your baby to make him stop crying. Place your baby in their crib and close the bedroom door until you calm down. It is okay to let your baby cry. Do not go back in until you are feeling better.
Other things to expect
It’s normal for your baby’s stools to have a pasty consistency if you are formula feeding. It's also normal for it to be a greenish color due to iron contained within the formula.
Your baby can focus more clearly with their eyes now and can track objects when they move. In the next month or so, their color vision will mature. This is a stage of rapid changes in your baby’s eyes which need to be protected from bright light. Avoid going out in harsh, direct sunlight if possible. If you are breastfeeding, ensure your diet is high in green leafy vegetables, yellow vegetables, and a wide range of fruits. These all contain antioxidants and specific nutrients which will help protect your baby’s retina against light damage.
