Baby wont sleep unless on me

[Charlit30]

My little girl is 14weeks old, she is still having bad gas pains thru her colic. I was waking up every morning at 4am to her crying in pain so I was laying her on me on her belly so she could sleep for longer while I stayed awake watching films so I didnt nod off. But now i have done this she will only sleep if on me, i try and put her in her next to be crib and she wakes up straight away and cries. I've tried the whole leave her to cry, reassure her, wait for her to calm down and walk away.... but she doesnt settle. As the time goes on she seems to get more upset than less.
Any suggestions? I cant keep sleeping every night with her on me, although I enjoy the cuddles it's not the safest of solutions.
I've tried heating her crib, putting my top in her crib so it smells off me🤷‍♀️

Have you tried baby massage classes? they really help if you have a gassy / refluxey baby

Yeah, I do it with every nappy change, before bed and 30mins after 3am feed.😑🤷‍♀️

My 15wk old DS has colic with bad trapped wind and he wakes at about 4am too. He sleeps in his snuzpod or in bed next to me until he wakes with his tummy. Then I put his head on my arm and his body down the side of my body (if that makes sense?!). He then usually wakes an hour later crying with tummy pain, I get out of bed and rock him a bit then he’ll settle for another hour.

I’ve tried absolutely everything and nothing works so I feel your pain. I just hope it ends soon x
