You might want to ask your pediatrician. Chances are, they know one who is close. I know many hospitals have sleep labs, and I'm sure they can make suggestions. If you have a Children's hospital near you, that might be a really good place to start. If you live in/near Chicago, there's a good Children's hospital out there with doctors who deal specifically with sleep disorders/sleep issues.
I know that between 3 and 5 or 6 months daytime sleep develops biorhythm-wise, and naps do get messed up as a result. The best thing to do is wait it out, do what you can to keep them rested, knowing that there is light at the end of the tunnel.
But I can certainly understand the frustration, as I'm dealing with it myself. My previously well-rested child is becoming increasingly overtired, and I feel helpless as everything I try only seems to make things worse, making me a nervous wreck and my DH feeling helpless as to how to help either of us.
Do yourself a favor though...start keeping a sleep diary of naps and nighttime sleep, noting breaks in sleep, if you haven't started already (if you do see a sleep doctor they might want you to do that anyway for at least a week). I've been doing that for a little over a month, but I just looked back at the last few weeks when this whole mess started, and realized she's getting more sleep in a 24 hour period than I thought, giving me some small sense of comfort. Often we think that things are worse than they actually are because all we can remember vividly is the time when things were bad, especially in recent memory.
And something I've started to do...tell myself to look at the big picture instead of looking at the day to day. So they don't sleep well for a week or 2, maybe 3...ok...that's 2-3 weeks in a lifetime. It's got to get better at some point. I'm a pretty bad pessimist a lot of the time admittedly, so it takes a lot for me to do this, but somehow it helps :roll:
Anyway, hope this helps a little...sorry so long
