Thank you Sianie.
Yes, he is theeting right now as well. But before when he was not he was waking up around 5:30 am as well.
Yesterday the bedtime was around 8:20pm (as his second nap ended around 4 pm) and he still woke up today around 5:30 am. I fed him around 6 am and he finished the enitre bottle quickly. I think he might be going also through a growth spurt. Oh ...I wish they could talk.........and just say what's wrong.
So when he had only 9 hours of night sleep and woke up at 5:30 am how long should I wait till the next nap. Is 4 hours too long.
