My daughter will be 6 months next week. She has pretty much been STTN since about 3 months (once in a while will wake up a couple of times but go right back to sleep). She is on formula and we dream feed her at 9 pm and she hasn't had a middle of the night bottle since 3 months. Since DLS, she has been waking extremely early- between 4 and 4:45 am. We have tried putting her to bed earlier, later, more nap time, less nap time. We've just been rolling with the early wake ups but I'm starting to get exhausted. I tried giving her a bottle this morning at 4:30, kept lights low, tried rocking her- she yawns and rubs her eyes but will not fall back asleep. We at least used to be able to get her back to sleep and just co-sleep to a more reasonable hour but that's not happening anymore. She is teething but it doesn't seem to bother her- she wakes up happy and wants to play. Any suggestions? She generally goes to sleep between 6 and 6;30 pm and naps total about 4 hours. Thanks!
