Hi A.,
Most docs recommend waiting until at least six months to lessen the chances of developing allergies. The Lucile Packard Children's Hospital website has more info on this, as does the Mayo clinic. Also, please keep in mind that eating solids can often stimulate tooth growth, as you apparently have already discovered. Teething disrupts sleep. Sleeping through the night at your daughter's age really is just five or six hours (I was so ticked when I learned that!). With my son, his sleep improved as he gained weight and got worse when he was teething or approaching a developmental milestone (such as sitting up, pulling up, talking, walking). From all I read, sleep disruptions often go hand in hand with both teething and developmental milestones. My son was never a good eater (still isn't) and we didn't give him any solids, including cereal, until after six months, but his sleep was well within the normal range -- actually even a bit better. However, he did have severe reflux, and until we controlled it with meds, we had many nights of him screaming in pain. Silent reflux can cause lots of pain, too. Is the head of his crib propped up? Reflux isn't just an issue of liquids coming back up; often the whole digestive system is not moving in a systematic way. Constipation and reflux can come hand in hand. We had to treat both simultaneously once we started solids. While solids are less likely to come back up, that doesn't mean that stomach acid won't. Plenty of adults have reflux, after all. Unfortunately, there are not very many pediatric GIs, but there are one or two great ones at UCSF, and I'm sure they have some at Children's Oakland. I don't know anything about hospitals closer to you, but you might be able to find someone good in the Sacramento area.
