HELPPPPP !!!! She has a lot of gas. what do I do to relieve it besides burping her and doing some leg and hip movements . she's screaming on the top of her lungs for past few days . I thought maybe she was sick , took her temperature and it was 98.3 yesterday . she falls asleep and when I put her in her bassinet she will wake up 5 to 15 mins later .. my mom is telling me it's her gas . she passes gas a lot and it sounds like a lot but I don't think all of her gas comes out .
