Just as the title says. How did you get through the 4 month sleep regression?

I think we are in it now (first I thought it was because he was sick, which it could've been, but he's better and his sleep is not). DS fought bedtime for almost 45 minutes tonight, and has since woken up 3 times in the last hour and a half. Ugh. I have just been nursing him back to sleep. Usually in the early morning I just bring him in bed with us. His naps suck too! I don't know what else to do! Sleep training may be in our near future!
