Tell them all to get stuffed! Its your baby so you do what you want! People will find any reason to criticize mothers...I get it from my family all the time. Just don't listen and certainly don't let them put you off breastfeeding..its the most wonderful special bond you can have with your baby.
Right now its christmas day and I've left the in laws to come in to feed my son to sleep and its the nicest way to spend a few minutes away from everything!
