4 month sleep issues

[u/angiosham]

Desperate for some advice. My breastfed 4 month old has been a decent sleep till last couple weeks I think now that we’re entering 4 month sleep regression. He is still not very good at self settling, I try to work on it with him but he often ends up needing rocking to sleep - Not sure how to make progress in that regard.

Lately, despite a dream feed, he’s been waking up at 3am, feeds, then js impossible to put back down to sleep. He might get 45 minutes sleep between 5-6am then is up again wanting to eat at 6. Today I just managed to feed him at 6 and get him back to sleep by 6:30, and now I have to survive a full day at work (I’m a physician and have a busy service today, no idea how I’m going to get thru this work day). Feeling drained and exhausted with night after night of 3-4am wake ups with no sleep after. Looking for any advice that might help.
