Hi! Yes it could be growth spurts or teething(if u see it swollen).U can give some cooling item for him to bite to soothe his gum during the day. My son only wants to be held and cuddle while sleeping but it will go away after around 3days - 1 week. I will let him have his naps during the day so he won’t be tired easily at night. Try to comfort him during these time it will pass by before u know it.
My baby is also 11 months now, she cried every midnight & I need to carry and pat her too. She fall asleep I put back to her baby cot sometimes she cry again. Previously she can sleep overnight. It has been a week she cried every midnight too. Not sure is teething or stomachache.
Yup sounds like growth spurt/ teething problem. But growth spurts can occur again later
