Kitsmom-
My baby sounds identicle to yours! 3 1/2 months old, 20 minute naps. He is on a 3 hour EASY and is also teething. I cannot get him to take a long nap except in his swing! I'm going crazy because I barely have enough time to eat and get dressed.
I tried putting him down at first yawn, but as soon as he knew it was time to nap, is wide awake and not the least bit interested.
Sleeps pretty well at night, usually getting up once. I am wondering if it's a 3 month thing, a teething thing, or just my fault that I cannot train him properly. I don't have the pu/pd thing going yet. He gets hysterical if I do that and chokes because he cries so hard. I am still rocking, marching him to sleep. I've ordered a new hammock bed for him so waiting for that to arrive before I start training him to sleep on his own.
He sleeps in his CARSEAT because he has reflux. God help me!!!!! Does anyone else have this problem? He also turns over during naps and agitates himself.
