@Pinktruffle obviously I've never done it before but am intending to. You should not feel pressured into breastfeeding, but it might help to try and think about why you would prefer not to so you know why you've come to the decision. You shouldn't have to defend your choices to anyone but it's good to feel secure in your choices.
Personally I feel the opposite about formula feeding, sterilising, preparing bottles, getting the temperature right, always having to have the equipment with you if you go somewhere, the cost of formula when breast milk is free, having to keep track of how much you feed them so you don't overfeed. So for me, if I can get the hang of it, breastfeeding seems like the easier of the two.
But that's why it's so important that everyone considers their own preferences. You definitely should not breastfeed because someone else makes you feel you should if you don't want to though.
