R.D.
Instead of giving her more than her little body can handle, simply do one of two things (or both!):
1- Lay her belly down on your arm, and gently swing her. The counter pressure on her tummy will make it feel better, and the swinging soothes.
2- Lay her on her back on the couch or your bed and sit at her feet. Slowly bend her knees and gently press them to her belly. Again, the counter pressure gives relief, and the position she'll be in makes it easier for her little bowels to pass gas.
You know how when newborn's have their bottom wipes, and more comes out? If push comes to shove, you gave gently apply pressure with your thumb (covered with a wipee) to her anus; this gets things going. Infant suppositories can help as well.
Speak with her pediatrician if the problem persists through out the weekend. Hope your little one feels better soon!!
