was just about to post with what we did, but Lolly explained it much better than i could have!!!(FWIW, & a slight aside, but she also held my hand & guided me in the right direction-time & time again while i figured out the whole FF-thing!thanks again Lolly!DD has you to thank for not being poisoned!!!!)
i foudn it handiest to use the cartons of formula if we were out & about for a feed....they are more expensive, but it was stress-free,iywim!?! i used to buy them in a specific pharmacy(not sure if i can say the name!?) so that i was collecting points at the same time & didn't feel so guilty about taking the "short-cut!"
