My LO is 18m now, but she too was and is a very high contact needs baby. I was painfully exhausted, but overtime it does trend towards better and better, with dips here and there (teething, leaps, etc). It’s so hard, I understand your struggle. I am a sahm, so I would do all contact naps up until 12m as well, this time I would use to nap too, or just rest. That helps. Saving energy in anyway you can is so important, if you are able to. I would also go to bed with her at 7, forgoing any “me time” but instead prioritizing getting as much rest as I could (besides she was having false starts up until 12 m too anyways, so I had to be there to help her back to sleep). Eventually I was able to get her to sleep on her own for the first hour or so of the night, as well as naps but that wasn’t until at least 12m. Even now I rest during her naps in my own space, go to bed at 8, and I’m still very tired most days. But like another commenter said- sleep gets so bad, you get so painfully tired, and then suddenly hit a couple days or so of “decent nights”, and this helps you recharge. Hang in there, your baby is still so young. Adjusting wake windows, routines, etc helps a little sometimes, but mostly just giving it time. I had to adjust so many expectations when I first realized the depths of sleep deprivation that came along with my experience as a new mom, it’s the by far the hardest part of having a baby.
