I found it much easier than I was expecting tbh.H is 2 years and 3 months older than M, which was a nice gap.He helped me look after M, getting th changing matt and bag things like that.I breastfed M but H would sit by us on the sofa and have a drink from his cup.My 2 are close, and they have always been together, its not harder to have one more imo.
There is only 15 months between myself and my brother, mum had sections both times and didnt breastfeed but she said it was easier to have 2 of us.
