Ivy usually goes once a day. Yesterday it was runnier than normal but was okay all day. Today she went this morning it was stinky and overflowed her nappy she went again 3hours later again very runny and smelly and now shes just been again and it had white lumps and was very yellow and kind of stringy it was like clear yellow too. Shes only formula fed. She seems happy in herself just she normally wouldn't go that much and it really is runny. Anyone know what it might be?
