I formula fed (after giving BF a shot). I didn't seem to experience any of the hang ups that many women do when they switch to FF. I had fully intended to EBF. The reasons that I can think of for not experiencing any issues with switching to FF are:
A friend who is a pediatrician said not to get too hung up on it if it doesn't work out as she has seen lots of parents giving themselves an unnecessarily hard time for FF or putting themselves and their DC through a massive ordeal trying to continue BF when it wasn't working. While not the first choice, this made me consider FF an acceptable alternative. I actively chose not to get hung up on BF and some might suggest that this was why we did end up FF, but I don't think this is the case (medical issues are the main reason).
Having scientific backgrounds my DH and I were able to read research and abstracts of research on the difference between BF and FF and draw our own conclusions about the quality of the evidence and the strength of any differences found. The oversimplistic information presented in pro-BF literature is only helpful when making the initial decision to BF. It is less helpful when things aren't going well and actually detrimental once you have switched over. We were also able to research "safe FF" and make an attempt to unpick the problems with formula and the problems of badly made up formula.
The support of my DH, family and friends. No one has ever said anything negative about the decision to move to formula and my mother has spoken of her relief as DD was beginning to become dehydrated. Similarly my GP was supportive and there is no reason for HCP not to be once you have started to FF as there is no going back.
So what could you do? I think the main thing is not to stigmatise FF, but to make it clear that FF well is much better than FF badly. The risks from making formula up incorrectly are really much more significant that people imagine and lots of people don't follow the instructions. Formula feeding is probably also associated with other behaviours that aren't idea (e.g. very early weaning). I would like to see leaflets about doing your best for your FF baby.
