My 4 week old DD has really bad reflux therefore has difficulty breathing when laying on her back, especially in her Moses basket. I even got a reflux wedge that I put under the mattress to help her breathe but instead she was lopsided and still not breathing properly. She can sleep in her chair, so she has been the last couple of nights so we both get some sleep but I know that isn't good for her development etc. I'm not sure what to do about this🙄
