So DS showed signs of wanting to do the 2 to 1 nap shift at about 11m (refusing 2nd naps). I totally didn't think he was ready as he could only manage about 3.5hrs of A time before getting cranky. So for a while I 'tricked' him into a second nap by taking a walk in the stroller or something and he would sleep anywhere from 40-80min. He would sleep 10-11hrs at night too. At 12m we started daycare and he was so tired from that that we had no trouble getting him to take his second nap and still sleep 11hrs at night. Up until last week all was well but for the past week he has been waking up very early (4:45-5AM) and having a lot of daytime sleep (1st nap 80-120min, 2nd nap 40-80min). He still can't do much more than 4hrs of A time without getting crabby so I think we're still a bit away from doing one nap. I hate 5AM wake ups but can put up with it for a while until he is truly ready for one nap and can manage 5-5.5hrs of A time (with daycare).
My question is this: If I let him do this longer daytime naps and early wakings, am I in for a horrible time when we do go to one nap and try to slep in a bit later (am I doing some accidental parenting mistake here)? Should I just wake him earlier from his naps (i.e no more than 80min/nap)? Should I bite the bullet and go to one nap now?
Sorry for the long preamble but I wanted to give you the lay of the land.
