20mo all of a sudden doesn't want to nap. Normal?

[rrreow]

My 20mo DS has quite reliably had one daytime nap of 1.5-2 hours since he was about 12mo. However, the last few days he's not wanting to nap.

I have a small routine for naptime: nappy change, read a book, then I put him in his cot & I leave the room. This has always worked before, I could hear him playing/babbling through the baby monitor for about 15-20 minutes, but then he'd go to sleep. The past few days he's either not gone to sleep at all (he seems fine in his cot though, just babbling to himself and playing) or he's finally fallen asleep after 1.5-2 hours.

His nighttime sleep is fine at the moment. He's not ill and not teething either.

The biggest problem is that he really needs the nap. If he doesn't have it he will be grumpy/aggressive until bedtime.

Does this mean he's dropping his nap? Is he actually ready to do this? Any way I can encourage him to nap?

You could have been talking about my DD - exactly the same age, and had exactly the same thing the last couple of weeks. I've tried pushing her nap back slightly later (to 12.30/1) rather than 11.30/12 which seems to have worked.

Always wake her up by 3 though so she'll still go to bed at a reasonable time!

Agree with annabeldp i also had to shift nap later to around 1pm at this age. Lots of lo's do have a funny blip at this age tho, they suddenly stop napping & after a couple of weeks they start again, imo totally developmental. Hang in there the nap will be back im sure!

Thanks for your replies! Good to know. He has been napping the past two days, just taking a LONG time to go to sleep. Will try and push his naps back a bit at home (they're at 12noon at nursery though.. not much I can do about that - but perhaps all the running around he does there all morning means he's more tired anyway).
