I didn’t manage to breastfeed any of my three dses, @Cherryhill22 - in fact ds2 ended up in hospital because he had lost so much from his birthweight and hadn’t regained it at 6 weeks old. I felt like the worst failure as a mum, but when I look back, I can see I did my best.
Breastfeeding is a great thing to do for your baby - but there are so many other good things you can do - weaning them with home cooked food, cooking healthy meals as they grow up, encouraging them to have fun and exercise, reading to the, supporting and encouraging them to learn new skills - the list goes on and on.
And formula is a perfectly good way to feed a baby - as other posters have said, a happy, relaxed mum is better for the baby than a worried, stressed one, so if formula feeding means you can be a happy mum, then it is the right thing for you.
I will also say that my three boys are all grown up now - they are healthy, happy, well adjusted - one is a senior quantity surveyor, about to buy his first house with his girlfriend, the second is a teacher, and the third will graduate next year.
They are all shining examples of the truth that formula fed babies can, and do, do just fine.
