Twins were born 16 days ago. Twin1 weighing 3.26kg twin2 weighing 2.45kg at 10 days twin1 weighed 3.21 and twin2 2.41 and at 16 days (today) twin1 has gained and is 3.39 and twin2 has lost and is 2.40. Midwife did lots of shaking of head but didn't explain if this was something to worry about or not or what it coudl be. Is this really bad? The twin2 feeds fine, is very alert and has plenty of wet nappies, she doesn't poo often but when she does it is nice and soft and yellow. I was feeling really optimistic and confident but this has knocked me. I feel a bit emotional!
