Coming to this a bit late :)
Thanks for the nice things said about how I post, 4madboys, but I have been called patronising, extremist, aggressive and militant many times on mumsnet by some of the posters here on this thread, too.
Obviously, I plead innocent to all those charges!
I think is is reasonable for someone close to a baby (this is the OP's neice, after all) and also pregnant and looking forward to breastfeeding herself to have these feelings on seeing a baby remaining uncomforted and in distress. If this baby was being breastfed, the 'pass the parcel scene' of everyone having a go at feeding would not happen, and the baby's physical and emotional 'overtures' to his mother would be responded to.
It's not reasonable to judge the mother because i) she has the right to use her body how she wishes and ii) she may not have been given the opportunity to understand the needs of a newborn
I wish that everyone who formula feeds, for whatever reason, was helped to appreciate that some of the 'advantages' of formula feeding are actually drawbacks, and then they would be able to make a decision on full information. They would still have the right to decide, of course, and the right to support whatever their decision.
But they would at least not be under the misapprehension that (as one poster said) 'it's only food' and that therefore we should not be bothered one way or the other - which is a notion that is so, so, wrong.
Feeding, however it's done, bottle or breast, is part of the 'territory' where early relationships develop. It's not the only part, but it's an important part....and it can be done (bottle or breast) in ways which enhance the baby's experiences, and ways which do not. The baby does not have a choice, either, and this makes the balance of power skewed towards the mother - who can decide to redress it and equalise it, by feeding in a way that acknowledges the baby's normal, healthy needs for responsiveness, gentleness, contact and peaceful, consistent, loving interaction.
If you see that not happening, why would you not be sad for the baby who's missing out?
