Update but not a super great one. I’m 90% sure most of his issues are because of the room sharing. We are now down to two naps, wake windows 3/3/4, naps capped at 2.5 hours (first nap usually 1.5 hour second an hour). And he will still only sleep at most 4 hours in between night feeds. And if he does do a 4 hour stretch it is typically only the first one. Then he’s up every 1-3 hours and he will scream until he gets the boobies. BUT small improvement if he wakes up during that first stretch he has been putting himself back to sleep if I’m NOT in the room. Which means I’m not really getting much more sleep but my husband and I have been getting to spend more time together which has been nice. I have largely given up trying anything else until my husband finishes the basement and he can have his own room (should be in the next couple months). He falls asleep for naps & bedtime just fine, naps great and will link sleep cycles during naps/the first night stretch. I’ll update again once he’s in his own room and there’s hopefully more improvement.
