Sleep - Reflux - HELP😫

Hello All, my second little girl suffered from felicity really badly from about three weeks old due to my let down being too fast, after trying all different positions for feeding and propping up sleeping and nipple shields etc etc I put her onto the bottle 😢 thankfully she seems to be much better for it in terms of reflux, and finally at four months just getting into a sleeping routine ☺️ the only problem is when she sleeps she is sooo used to being held and picked up all the time she is sleeping for 20 /30 mins max 🤷🏻‍♀️ Any advice 🤞🏼
