Is it normal for a 3 month old baby to sleep more than 10 hours a day?

My husband has been getting up at night to feed our daughter and coax her to sleep since she was born. She was able to sleep for 8 hours straight from two months old without getting up at night to drink milk. At three months old, she was able to sleep for 10 to 12 hours straight without getting up at night to drink milk. My husband is much more relaxed now! Of course, it is also because he and the aunt took good care of her. Let me share their experience.

Baby's sleep key points at night

How to make your baby sleep through the night: The most important thing is to create a good biological clock for your baby. This biological clock is: sleep at night. So the two key points we do are:

First: Let your baby know the concept of night

Second: You need to sleep in this environment.

How to create an evening atmosphere

1. We usually regard the baby's night after 7pm. At this time, she will stay in a dark room and start to sleep.

2. In the first month after birth, the baby was fed every three hours. During the night feeding, only a very dim light was turned on, and the baby was not looked at or played with.

3. Change diapers after nighttime feedings etc. are done quietly

4. On the contrary, interact with your baby more during the day to create a contrast between day and night.

How to let your baby sleep in this environment at night

1. Don’t hold the baby to sleep. They never let the baby fall asleep in their arms. They can hold the baby to coax him or put the baby in the bed to soothe the baby to sleep.

2. Let your baby get used to lying in his own bed, not in an adult’s arms.

3. Deal with the newborn baby's startle reaction and make the baby feel safe: use a wrap or sleeping bag, buy dockatot or sleepyhead.

4. If you find your baby sleeping for a long time at night, don’t wake her up to feed her. She will eat more after waking up to make up for the lack of milk. This is what the pediatrician here told us.
