I'm following the baby whisperer's (BW) strategy of EASY routine with my 13 weeks old son but I'm struggling with his naps. He goes to sleep well but consistently wakes after 30 minutes and I've read in the BW stuff that this is not long enough. If he's in his car seat he'll remain awake for a bit and then nod off again but if we're in the house he cries. Nothing seems to settle him back to sleep but he doesn't seem to want to be awake either as he plays if I try and play with him. Is it that he only needs 3x30 minute naps in the day or should I be trying to extend his nap time - and if so how? It's so draining spending approximately 4 hours a day trying to settle him back to sleep. Help!
