My son just turned 12 weeks old. He was such a great sleeper at night - sleeping 12 hours straight, which was obviously wonderful. He has been more difficult lately - when we put him to bed he has been waking up every 20 minutes or so. Once he is officially asleep he is waking up around 3 and I feed him. His naps are awful as well. Instead of 45 minute naps I get 30 minutes. I sometimes hold him for a two hour nap just to get him to sleep well...I know - not a good habit!
Anyway, I don't know where to start and need some help.
If I do the wake to sleep method do I do this for all naps? Do I start with just one nap? If he wakes at 30 minutes, do I go in at 20 minute and do wake to sleep?
