Hello, How are you❤️ I wanted to ask, the child often wakes up at night, 8-10 times. He used to wake up only 2-3 times and that was it. Now he's tossing and turning, I give him a breastfeed, and he falls asleep immediately. Then after 30 minutes he wakes up. And so on until morning. Is this because of teeth? Or is there something wrong with his body starting to hurt? ???? or some regression? What can be done??
