LO is 6 months old today, and for the past few days has been having really abnormal sleep problems at night. For some background, as of a few weeks ago he would normally wake once around 4am for a feed, but other than that he would sleep from about 7:30pm-7am without any other wakings. We even had 2 consecutive days about 2 weeks ago where he slept all the way through and didn't even wake up at 4! However, last week he came down with a cold and also got an ear infection, so sleep was understandably a little off then. Now he is over the cold and ear infection, but his sleep problems have gotten much worse. He is waking every 2-3 hours now and is very hard to settle back to sleep most of those times. The last 2 nights he has woken around midnight, 2:30am, 4:30am, and when he woke around 4:30 he was pretty much wide awake and it took close to an hour to get him back to sleep. I also tried nursing him when he was upset and wouldn't settle (I don't like to do that because I don't want to go back to old habits), and he would calm down, but he wasn't really drinking much milk. It seemed more like he was just nibbling for comfort. Two other things that have changed is that at day care he wants to be held all the time and they have a difficult time keeping him calm, and he gets upset now when I try to feed him solids. He was eating them pretty well a couple of weeks ago, but now he turns his head almost immediately and cries.
I'm wondering what could be going on here. I have a few hunches, but was wondering if any other experienced moms can look at his behaviors and have a good idea of what's happening. I'm guessing he is either teething or he is going through the wonder week 26 and that is disturbing things? Or maybe a combination of both?
If anyone wants to chime in and give me any ideas I'd appreciate it! I would post his EASY routine, but the days he is in day care it gets all out of whack because he doesn't nap more than 45 mins at a time there. It's always been that way, and I've just come to accept that that is how it will be on his day care days. He had always been fine in the past with it, just this week that things have gone wacky.
