Hi Sam,
ok finally weighed them this morning.
2 of the girls are at 2.9 oz, the boy runt and other girl are 2.8 oz.
Eyes not open yet.
So thats between 79 to 82 g each.
5% of 80g is 4g = about 4ml of formula, right ?
We've been feeding them about 3 to 3.5 ml each, and one of them wanted more this morning so she got 4ml.
