I'm pregnant and planning on bottle feeding from the start. I feel no guilt for that, its the right thing for my, myself and my husband.
I'm fed up of people judging already. People that have for the most part not done the research into breast vs formula that I have. When its come up in conversation that I'll be bottle feeding, I've had to fend off a barage of questions from friends already. I've never asked them why they want to breastfeed, and whether its the right thing to do, so perhaps they should offer me the same courtesy.
Even here, when someone is asking for support (ignoring that she may have been a troll), instead, she gets criticism and judgement from some people.
The benefits from breastfeeding are marginal, and limited to a few things like tummy bugs and ear infections. The other benefits that are spashed about in the media either come from horrifically poor studies , for example ones which don't take into account socio-economic factors or are very theoretical, and not backed up by actual data. For example, I had to laugh at a study on formula and tummy bugs - they were comparing formula fed and breastfed infants in the slums of Lima. Clearly a slum with questionable drinking water and poor access to sterrilisation is exactly like the UK...
But you shouldn't just look at the physical benefits and drawbacks, but the wider situation. The ability to share the feeding, so that mum is able to sleep, is a massive advantage. That mum can go back to work earlier if she wants, without the faff of expressing is an advantage. That dad gets some extra time bonding with his child through feeding is an advantage. It means that mum isn't tied to the baby 24/7, which is very beneficial for a lot of women's mental health.And thats before you get to the discomfort of breastfeeding initially, cracked nipples, scarring, mastitis. A happier mother is more likely to have a happier baby.
From formula feeding at the outset, babies are less likely to become dehydrated. Babies have died from waiting for mum to produce enough milk.
There are advantages and disadvantages to both. Its really up to the parents, and no business of anyone else.
