Personally - an im not having a go here - but i think its quite selfish not to at least give breast feeding a try for the first wee while. The baby gets an untold amount of goodness from the breast milk that just doesnt happen with formula - and generally the reasons for FF from the very start (and im not talking here if you cant due to medical reasons) benefit mum - i.e. not being tied to baby, sharing night feeds etc.
Also - as much as we can all tell you, every mum and every baby is different, and you wont know if it suits you both till you try. Becky - the breast feeding guru in baby and toddler - was all set to ff if i remember rightly, and is still breast feeding her LO who is about 4months through times where a lot of women would have given up.
