Lo is almost 8 months old his naps are getting shorter he just also recently started holding his bottle on his own (sometimes). Starting to get that deep belly laugh. He always goes to sleep around 11 the latest and usually sleep through the night but he woke up at 3 am talking to himself and then fell back asleep ten mins later has this ever happen to you. Just curious maybe it’s a growth spurt.
