hey mamas, thanks for the info. i bit the bullet and just gave him the formula bottle and he took it - no problems. i think the curiosity was killing me, plus my milk supply seems to be diminishing despite constant pumping and fenugreek, etc. it's like it has a mind of its own and is going the wrong way. anyway, knowing that he'll take the formula if i need to supplement is a great relief.
all the best, kim
