Liam is an AWESOME night time sleeper. Started STTN (8 hours) when he was 10 weeks old and increased from there to where he now sleeps for 11-12 hours consistently every night. He never went through the 4 month wakeful, has never been awakened by teething, and even when he had bad bronchiolitis he STILL STTN every night.
I almost feel guilty about it. I read so many posts about babies who are still not STTN. I really do almost feel bad that I got lucky!
