My son is almost five months now and for awhile there he would scream so bad it would almost make you cry. He was up sometimes half the night....at times 2am or so. I was going crazy. So on the worse nights I gave him 1 ml of maloox. My sister-in-law had a son with acid reflux and that was what she gave her son. We were working with a doctor to find out about the acid reflux issue, but found with the maloox it had simethocone in it and it worked. I only gave it to him a few times. We tried the infant drops and that didn't really help. The Tummy Soothers helped some. And the Gripe Water helped better....but still not perfectly.
He's gotten to where now he can push the gas out himself. He will really strain and fart up a storm now. He's so gassy poor thing. I tried eliminating everything that might cause gas...for me that's just about everything I eat. So it was hard. Problem is it didn't help. I even took Beano everytime I ate. No help. I have noticed that certain things make the gas worse...like raw onions, bananas, certain beans, old eggs...but that just increases it more.
I'm afraid that you will just need to pump her little legs at night, give her the infant drops (it helps a little and won't hurt her..my oldest got them constantly...she was full of hot air as well), and then just pray her belly gets use to the gas quickly.
I pump my sons legs now when he starts to squirm. I touch his toes to his nose one at a time...he thinks it is quite funny. And the gas just shoots out. I do that for a few minutes and that gets the bulk of it out.
It will get better...it's just painful waiting for that to happen.
I feel for you.
