I'm exhausted! Mentally and physically. My baby was sleeping so well, but now she's up at 2,4,6, & 8am. She sleeps in her crib until 2am when she refuses. There was a time that I could fall asleep instantly, but sometimes I am awake until she wakes up the next time. I feel my body breaking down. I'm wondering if it's time to sleep train. My only concerns is that she's teething and has bad acid reflux (Doctor increased her meds today - praying it helps!! We are about to go on vacation, but i would like to sleep train afterwards. Any advice?

We both work full time. We are both falling apart. Any advice to help??
