My daughters the same and we even used a sleep coach. I would consider 1 wake a really good night! She is similar in that she wakes up hungry for a feed as she eats like a little sparrow during the day so that’s obviously a big part to play in it. She does tend to go back to sleep fairly easy as long as you get to her quickly. Me and my partner both work full time so we just try and take it in turns around who has an ‘easier’ day the next day. We have tried everything so just hoping she will grow out of it when she starts eating more. I have heard other mums says their babies wake up and are up for hours in the night just messing about so don’t worry your not alone.
Remember waking in the night is super normal at this age! I appreciate being up for 2-3hrs isn’t as normal, maybe look at daytime sleep? My daughter wakes a few times, we bedshare and bf so she settles quickly with a boob in her mouth and I don’t mind this! So it works for us :)
You might want to look at shortening the day time sleep and perhaps looking at moving bed time a bit later?
I’d try capping the nap for a few days and see if it helps. Cut off 15 mins and see how it affects night sleep after 3 days, and if you need to you can cut off another 15 mins.
If it helps we had this for a few weeks and he is now sleeping through again - so hope the same for you x
