My DD never napped well, but she started when she went to
daycare. I am positive she just wants to stay up to hang out
with me. I nurse her to sleep, put her down, she seems deeply
asleep, and I walk away. Then, I hear her crying. I go in, and
look down at her and she gives me the biggest grin ever!  It is
hard to give up the idea of getting anything done. Harder still
is knowing she is going to be fussy later in the night.  On days
when I feel like an incompetent parent, I take DD and go
somewhere or do something. If she isn't going to nap at home, I
might as well do something fun.  You aren't the only one! But at
least your DC has good taste - wants to be with you!
