I had my DD 14 days ago an she started off being BF but is now FF. since last week she has been constipated and it is heartbreaking seeing her cry in pain when having a poo. She is currently on cow and gate comfort milk (did start on cow and gate newborn) but it doesn't seem to be helping. Doctor says to go back in 10 days if she is still bad but I'm wondering if changing to a different brand of formula will help or if anyone has any suggestions of what I can do to help. Iv tried massaging her tummy and doing bicycle legs but nothing seems to help her.
