Due a little girl in 15 weeks, planning on breastfeeding. I had a lot of issues breastfeeding my first as I have inverted nipples and I'm really worried that it's going to be more difficult to breastfeed this time as I'll have a 4 year old to contend with too. How do you mummy's cope with breastfeeding when you have other children? Thank you :)
