Hello, could you please tell me how to put a baby to sleep at 9 months old and what kind of daily routine should be followed? He sleeps twice for 1-1.5 hours during the day (from 2:00 PM to 3:30 PM and from 6:30 PM to 8:00 PM). I put him to bed at 11:00 PM and he wakes up every hour throughout the night, he is not breastfeeding anymore, I give him a bottle with milk at night, but he still doesn't sleep well. He already has teething before bedtime, so we give him medicine, but he still doesn't sleep well. He starts sleeping more around
