My daughter is almost 21 weeks old now, and we started the 4 hours routine about 2 weeks ago after reading the baby whisperer book.
Before that there was no routine at all.
For the last few days it seems that she got used to sleeping 1.5-2 hours in the morning nap, but in the 2nd nap she always wakes up after 15-30 minutes, and I can't put her back to sleep.
She cries a lot, and PU/PD and the other methods don't seem to help. With about an hour and a half until the next feed it seems like forever.
I keep her in her crib for as long as I can.
Seldom she's calm and talks to herself when she wakes up.
The same happens on the 3rd nap, except I don't insist on keeping her in the crib since that nap's supposed to be a short one.
Please, can you advise?
