Hi Bellymum! My lo is 5 mths and 1 week! He just started his napping only about a week ago! He used to nap maybe 30-45 min and then cry and not want to go back to sleep. I don't know if it is just him getting older that is making him nap longer or the fact that we have successfully got him sleeping in his crib exclusively when he used to sleep in our bed or in our arms for naps. Our schedule is as follows:
6:30 am cereal and bottle
He then usually plays for about 2 or 2.5 hrs than I put him down for a nap.
He will sleep up to 1.5 hrs.
More activity
10:30 am veggie and bottle
Plays again for another 2-2.5 hrs (I can tell when he starts rubbing eyes and getting really cranky that it's nap time!)
Sleep for up to another 1.5 hrs
Activity
2:30 pm fruit and bottle
Activity
Car ride or walk in stroller for catnap (about 45 min)
Activity
6 pm bath time
6:30 pm bottle
7 pm bed
The only things I have set in stone are the feeding times and bedtime and wakeup time. They are usually like clockwork. I just go by how cranky he gets as to when to put him down for a nap. A little trick I do is when I think he is tired, I lightly run my hand over his forehead and down his face barely touching him and he will close his eyes and keep them shut for a second or so if he is tired and fling them back open if not. It might seem weird but it works! Hope this helps!!
