my lo tend to cry during sleep in the afternoon. very hard to wake him up and calm him down. any solution?

I read that when babies wake up crying, it is a sign that they have not had enough sleep and need more rest. It could also be related to a child's temperament. In these cases, if the crying is not related to hunger, diaper change or illness, sometimes it is best to wait a minute or two when you hear crying. Sometimes, your baby will go right back to sleep. And when you finally go to comfort baby, at least you’ll know that the crying was due to a lack of sleep.
