Have you thought about getting a baby sling, wrap or something to help take some of the weight of your arms, and maybe see if anyone has a hammock you could borrow and see if that works, to give your arms a break. But yeah you do what you have to, so that bub is happy and mum to.

My sister thinks I am odd as I wear my little one alot on my back as it lets me get other stuff done and she is happy there. So yep do what you need to do and don't worry about what others say.
