My baby is 1w 3d she had hiccups in the womb a lot. Now that she is here every time we feed her she get them. I do 2 breastfeeding bottles in the morning and formula for the rest. She had problems learning how to suck and she always breathing with her mouth open. I use Dr. Brown bottles. The doctors and nurses said she was fine but we haven't had our 2w check up yet. Is an other moms having this same problems.
