In other news, I've suddenly started to go crazy!

DS is 9 weeks. Right before Thanksgiving he started waking more often at night. He HAD been sleeping a 4-5 hour stretch, then 2-3 hour stretches till morning. Now he sleeps a 3 hour stretch, a 2 hour stretch, then is awake 1-2 hours (not fussy, just awake), then sleeps VERY restlessly, waking every hour. He's also stopped napping, going from 3-4 hour plus naps to 4-5 20-30 min naps.

What is going on?! I thought maybe a Wonder Week, but it's been almost 2 weeks. He also got his 2 month vaccinations, but had no fever. His nights didn't get really bad until about 3 days later.

Some other things: he is getting worse at nursing. He was excellent, now he pulls off after every suck & fusses to get back on.
: I tried eliminating dairy around a month ago because of spitting up - it made no difference. I've been having small amounts of dairy with him sleeping fine for a few weeks before this started.
: He's always been kinda grunty & kicky around 2 to 5 am, but stayed asleep or would fall back asleep after nursing. Now he starts grunting & violently kicking around 12, he won't settle until he's fully awake & then he's happy - smiles all around!
: on Friday I started trying to put him down for naps so he can get used to not being held when daycare starts in jan.

I know this is crazy long,but does anyone know what's going on?! Or what I can do? Is this a normal thing to alter sleep so drastically for the worse? I went from around 7 hours sleep in good stretches plus an afternoon nap to around 4 hours sleep in 30-60 min stretches. DH leaves on a business trip until Wed & I am terrified!
