DD started these d@mn short naps at 8WO - a little over 2 weeks ago. Haven't battled as long as you, but I feel like I'm going completely insane over it. Went through the "I-can-fix-this" stage, then the "just-go-with-the-cranky-baby" stage and now I think I'm at the "I-don't-care-if-it's-accidental-parenting-she-needs-a-long-nap" stage. If it's truly developmental and she won't grow out of it until she 5+ months old, I'm sure I'll have to be committed! I've had no success extending any naps using Wake To Sleep. Not often, but sometimes I have been able to get her a "second" nap by getting her up, changing a diaper or other activity for about 10 minutes and then winddown and back to nap.
Why does it seem so easy reading the books? I've been doing some reading on naps and Tracy says to to PU/PD (am assuming pat/shh for younger LOs) to help them learn to get to the next sleep cycle. She says to do it until the next feed if you have to. Really?!? Has anyone had success with this?
