I am trying to give a little water to my dd2, especially in this heat. She is very constipated and i have been advised by NHS direct, docs, mw and hv to give some water. I have tried avent bottles, nuk bottles, spoons, cups, avent non spill, and plastic syringe. But she just will not take anything else, but the breast. It was not this hard with ds1. Its been a week now. Any suggestions?
