My daughter is three and a half months old, some days she does not poop, some days she poops once, and some days she poops 6-7 times a day but it is a soft phlegm type. For example, the day before yesterday she pooped once, yesterday she pooped 4 times a little and today she pooped 6-7 times a little and it was soft phlegm type. My daughter only eats Aptamil Gold 60 ml 2 to 3 times in 24 hours and the rest of the time she drinks breast milk. Is there any reason to worry about this?
