Silver,
thanks!
Andrea, yeah, the sleepeasy solution book we have is basically the Ferber method. If we do it, that's the technique we will do.
Jen, the problem is that the people who are anti-cry-it-out will tell you that it WILL permanently scar your kids, and there is no definitive research on the subject (believe me, I looked -- there are only self-reported results with no control groups for comparison). I don't really believe that they will be permanently scarred but I'd feel better about it if there was a cohesive study proving it. And it's just hard to listen to your baby cry when you know you could go in and calm her down, which is why they say cry-it-out is harder on the parents than the child!
In any case last night the prunes worked on A and she had a big #2 right before bed, then slept from 6-4 without any intervention required, so maybe the constipation was the problem after all.
C meanwhile started crawling around and talking to herself at 2am then got angry when she couldn't manage to grab her pacifier that she'd knocked into the corner of the crib, and we had to go pop it in her mouth for her (after which she instantly fell asleep). Still not quite sure what to do about the 4am waking -- they're hungry, but they're not really ready to get up. Ideally they'd sleep until 5 or later, then get up and eat. Perhaps we need to feed at 4 and gradually reduce the amount or gradually shift the time later.
Sorry to derail the conversation with my babies' sleep problems! In other news, we got about 7 inches of snow last night so I'm working from home today. The main roads are probably clear enough but they haven't plowed our neighborhood yet.
Edit to add -- I can't remember if I mentioned it or not, but we did get the baby gates up and gate off a playroom downstairs. It is 10000% better than the situation we had before! The babies don't care which room they're in as long as they have their toys and mommy or daddy, and Carter has been amazingly good about it and seems happier with the girls gated away. He whined for a minute the first time I went in there with the girls but then wandered off and took a nap on the couch. DH tells me yesterday during the day Carter was very relaxed and did his usual migration between his dog beds and the couch all day, spending some extra time in the front hall where he could keep an eye on what was going on in the playroom.
