I posted a big whine session about this too, but I just thought of something. Do you think that 5.5 months is too young to begin to do the two big naps and maybe a catnap? I'm thinking that the fighting and 30-45 min naps my dd is doing may be due to that fact. I don't think I overstimulate her, but I know she gets overtired by the end of the day from poor napping. Sometimes she'll even nap well in the early afternoon and still wake tired. But how do I get her to the 2 naps and catnap stage? Do I still extend for 15 min, no matter it she appears tired or not, because she appears tired from 1 hour or 1 1/2 hours on? I would love for her to do the 9am, 1pm nap thing. And then maybe a catnap. But I don't know when that develops, or how to "encourage" it to develop. Thanks for the advice.
