Hi, Paul is 15 mos and we have been on 1 nap for about 6 weeks. Just wanted to share a couple of our experiences in case it helps anyone, we have had so much help from this site! Paul does roughly 6:30/7 wake, 11:30/12 nap 2.5-3 hrs, 7:30ish asleep. Be warned we still have nightwakings but I think those are due to teething/AP.
Before this we were struggling with the afternoon nap even after limiting the am nap. During the 6 weeks we had 3 attempted 2-nap days when he woke before 6 am (2 in the first couple of weeks, 1 more recently). Frankly those were worse than the 1-nap days, most recently he was even sick and woke at 5:45, took a 45 min nap at 9 am and then only a 20 min nap at 2 pm. I think loving routine, at some point he decided it was just going to be one nap no matter how early.
The first couple of weeks were the worst, he was so tired in the morning. He had been doing about 3/3.25 hrs A time, but with the nightwakings he was starting the day closer to 7:30 so we went straight to nap at 11/11:30. At this time I'd still offer a nap at 9:30 but he'd refuse since he'd only been up 2 hrs. We stretched him out by taking LONG walks in the stroller (he won't sleep there or in the car) and giving him a small snack to munch on while we walked. He got half a lunch right before his nap and half when he woke up.
After a couple of weeks and 2 bad 2-nap days, I just figured we'd push through to 1 nap even with an early start time. So instead of offering a nap, we'd just have quiet time around 9, reading books or dozing if he needed it, heading out for our walk/snack around 9:30. After another week or so, our walk involved a stop at the playground where he would get out and play a bit -- playtime is getting longer now.
When we first started, his nap length was erratic, 1.5-2.5 hrs. If he woke at 1.25 hrs usually I could help him get back to sleep if I got there fast enough. After a couple of weeks, his naps lengthened to 1.75-3 hrs (again, assisted about half the time). Now he is starting the day at 6:30/7 instead of 7/7:30 but his naps have been on the long side. He has lunch right before his nap, if he is too tired to eat much before he goes down he just has a bigger snack when he gets up.
OK, hope this helps someone at least a little. Anyone want to help us solve our nightwakings
