I think in general, it's best to breastfeed if you have the opportunity to do so, but it's not that big a deal if it doesn't work for you and you rely on formula instead. Both work. It's great that both options exist, so you can pick which one works best for you. People get way too uptight about this sort of thing.

Not to mention that society is really hypocritical about it; demanding that women breastfeed, but also criticising them when they actually do so. Can't we give each other a bit more freedom to make our own decisions and trust that most people will be doing a pretty good job at it? Provide info, not judgement.
