He was sleeping a 5 or 6 hour stretch followed by a 3 to 4 hr stretch consistently from about 3 1/2 months to 4 1/2 months. We moved from FL to Vegas and he started nursing around the clock and having loads of sleep issues. His naps changed, he started sleeping less at night etc. I attributed it to the following: climate change (must be thirsty...), teething (lots of swollen gums episodes) and we also went through a bout with an ear infection. The thing is now we have a couple nights a week that are decent (maybe nursing every three hours) and then there will be two or three nights where he wakes up constantly (1 1/2 to 2 hr intervals). Oh and I reintroduced dairy about a month ago after not having it since he was 4 weeks and then took it out (ummmm mostly took it out) a little over a week ago.

Our sleeping arrangments: we have a co-sleeping bassinet that he has been in since birth because our bed was too small. Since we got a king bed (about a month ago) he is between the two. He usually starts out in the co-sleeping bassinet and is with us after we go to bed. He sleeps in his own space in the middle or some nights up against me.

The other thing I wanted to mention is that he used to go down at night and I was GUARANTEED he wouldn't wake again until it was time to nurse. Now he is very wakeful every night for the first two hours after I put him down. He is asleep when I lay him down (nursed to sleep or in the sling) and wakes up at a 45 min - 1 hr interval on the nose every night after he is put down. I either nurse or sway him back to sleep. Some times he does it 3 to 4 times before he settles for a couple of hours.

WHAT HAPPENED? Can I fix it? Will he ever go back to the 5 or 6 hrs without nursing?
