Gabriel didn't STTN until he was 1 year and 1 week old. He was waking to eat every 2 hours for the first 11 months. It started to improve at 11 months, then he hit a growth spurt for a week and went back to waking every 2 hours and then it improved again after that until suddenly at 53 weeks he decided to STTN. I didn't think I could do it because I was back at work full time since he was 2 months old. We have nobody nearby to watch him and I exclusively BF at night, so I had nobody to give me a break, ever. I somehow managed to survive and only lost half my sanity due to sleep deprivation. Needless to say, he's going to remain an only child.
