A very helpless feeling

Here I am. The grandmother of a 10 day old infant. Although I have been getting enough sleep, the 'every two-hour' feeding time has not yet bothered me. Looking at her face mesmerizes me every time I hold that little bundle of joy. She is such a good baby; always sleeps, never cries and has a great little disposition as of late. Both families are truly blessed with her. I am in charge of cleaning and preparation of the bottles. My daughter has decided to breastfeed but also use formula. We have already gotten the 'green light' from the pediatrician to do this. She seems to be satisfied with two ounces every feeding: one ounce of formula and one ounce of her mother's milk. But we have noticed something missing: it has been ½ a day since she has had a regular healthy bowel movement. I know this is not something one should blog about. If anything, I would love to hear some advice. I am in route to the store to get her some Karo syrup for her tummy. We tried gas drops last night but still little pellets are found in her diaper. She is having so much trouble staying comfortable that she seems to always lay on her side. Imagine what my little grand baby is going through....still...she doesn't cry about it.
