ds started doing the 45 minute nap thing when he was about 3 months. When he woke up after 45min he would be grumpy as he was still tired. So I started always trying to re-settling him. After a while he would occassionally re-settle himself and do 1.5hrs, with persistence 1.5hrs eventually became the norm.
More recently (now nearly 6 months) he has started waking at the 45 min mark again. Initially I didn't bother re-settling him as it was only occasional. Now it appears to becoming the norm again. It is not too much of a bother if he only does this once in the day but if he does it twice he gets very grumpy.
So I guess my question is do I need to be consistent in re-settling him again to re-establish the pattern or is he likely to grow out of this soon?
I am sure some mums will say to go with the flow but I just find 45 min naps make the day so awkward. Feeds are out of sync with naps so even if you only want to pop up the shops you know you will need to be interrupted by either a feed or a nap. Also by late afternoon if has only had 3x45mins he will be too tired to make it to bedtime but refuses point blank to go down for a 4th nap.
