has anyone started going through this with your current little one or another child? My girl is 3.5 months and has started sleeping pretty terribly. Shes soo hard to go down suddenly, wakes up a few times after putting her down, waking early. Last night she had a crying fit for an hour and we had no idea what was wrong. Thought maybe it was gas so we gave her gripe water, nothing worked. So my guess is this sleep regression may have started early. Or maybe its a phase?
