My mum was a militant formula feeder who thought breastfeeding was bonkers, akin to deliberately not having an indoor toilet or opting to do your work by candlelight rather than use electricity. I was formula fed from birth and rarely get sick. My first child was mostly formula fed (was definitely influenced by mum!). My second child was breastfed for a year and I'm still breastfeeding the 14 month old.
My first child gets sick the least and my middle child still constantly comes down with everything going! I love breastfeeding because I like foods that have gone through as few processes as possible. I think breastmilk is the biological norm but more so, I prefer the physical interaction with the baby. However, I think that formula is an amazing product that saves lives and sanity, and if someone wants to formula feed from Day 1 for convenience, so what!
As far as I can see it, the most important things for your child's development, aside from a form of milk they can get calories and nutrients from, are affection, sanitary living conditions, a varied diet as they grow up, exercise, childhood vaccinations and a positive, stable, emotionally nurturing home life. Breastmilk is a tiny component of parenting.
Breastfeeding completely ruined the early days of all three of my children. I couldn't enjoy any of my newborn babies. I'm glad I've done it but totally see why a woman wouldn't. Anyone reading this who feels guilty because they didn't or couldn't breastfeed: please take a step back and look at the whole picture of the life you're providing for your child. Your responsiveness as a parent on the day to day is basis, through the years, is more important overall.
Are breastfeeding rates in the UK pretty low? Yes. Are societal attitudes towards breastfeeding negative, compared to other countries? Again, yes, and that needs to change because the narrative that formula is the 'real' milk and breastmilk is the strange alternative is factually wrong. However nobody is going to embark on a breastfeeding journey because of guilt. Your heart has to be totally in it to get through all of the barriers and obstacles. Nobody should feel guilty for giving their child a safe alternative to breastmilk.
