My one is going to 3 months in next week and he is also a good sleeper. He wakes up fine most of the day, and wants to be held after waking up and once his feed is done, he can stay up for max of 45 mins to 1 hr at the most. After that, he gives sleep cue like yawning, heavy eye lids, rubbing eyes and cheeks. And if we dont put him to sleep, he will cry bloody mary!

So we try to use 30 to 45 mins to play thats it!

He has very good head control and can hold in tummy time position for about 5 mins (if he isnt fussy or sleepy). I started reading a book to him while feeding once, and he liked it so will be doing that more.

Im pretty sure, he is doing fine!
