Hey, so sorry not to have got back to you, just been away for a long weekend. More (((hugs))) sounds like you're doing amazingly well! I think most of us find it hard to adjust to being a family of four, but you've had a harder start than most, so go easy on yourself please, no mummy guilt required
Tbh I really would 'just' concentrate on doing what you can to ease the discomfort and helping him to feed and sleep however he can. Actually once he does get more sleep he should be able to relax more and then start learning how to sleep once you're all ready. If you can start to do that by 3-4mo then that's great, but as I've heard so many people around here say, if they're in lots of discomfort you can't really sleep train, they'll just associate sleeping with the pain which isn't helpful.
If you're worried about leaving sleep training too late, I'll share our experience with DD as a newborn, which involved two naps a day in the sling on preschool runs with DS, the third nap at home whilst DS had nap/screen time, fourth nap back in the sling, usually whilst kicking a ball around with DS, then BT once DH was home, so I did DD whilst he did DS. We didn't always get that third nap at home, due to appointments etc, but that was the only nap we did any sort of ST for, plus BT. And she still needed a lot of help (ie shh pat) with that one, until around 5mo, when she started self settling for 1st and 3rd naps at home. We didn't do this for reasons of discomfort but because I wanted to get outside with DS, but it worked great and all that sling use really didn't seem to interfere with her ability to self settle later. Remember, not all babies will really be able to self settling until 3-4mo anyway, before that they may need lots of shh pat or something similar. So if you can't do shh pat right now, really don't worry, make the most of being able to get out with DD using the sling and enjoy those extra cuddles with DS

Sorry if that's very rambly, does that help reassure at all? More (((hugs)))
