Ugh, my almost 1 year old was STTN for a few weeks when I sleep trained her a while back. She then started teething and got sick so we were back at square one. For the past month or two she has been waking up 2-4 times per night in the earlier part of the night (9-11pm) and then again at 4am. I feel like at her age she should be STTN or at least down to only one wake up. I'm getting exhausted though so I think I need to sleep train her. I have a hard time listening to her cry though. Any tips for me? I sleep trained my oldest LO but I don't remember it being so difficult...
