LO is 7.5 months old and she still doesn't STTN. We sleep trained her a few months ago and she was doing awesome, sleeping almost 9 hours before waking up...and I thought we won the battle. Now, she is back to waking up every few hours again. I thought it was teething, but this has been going on over 6 weeks now. I never thought I would have the LO who was up a billion times a night. I guess I'm just looking for others to say this is normal...or maybe some tips?
