Shit, I'm so tired,but there's no way I can even consider going to bed until I can stop weeping with laughter at the idea that I might force my toddler to nurse against his will.
Seriously now, and trying to be gentle: OP, you don't have to consider Bfing - or not - an older child right now. If, and when you become a mother, and if, and when, you decide to breastfeed (or can do it), you will realise how tiny they are for a long time and, moreover, how much they love and really do need BFing once they can walk and talk, etc. It is so good for them, not just nutritionally, but emotionally. When your child can't sleep, or they have a tummy bug and can't keep anything but breastmilk down, or they are in pain or v ill, breastfeeding is practically a miracle-worker. I do worry for you that you are considering making a parent out of a man who is so shocked at someone doing something as utterly mundane, normal and healthy as nursing a young toddler that he is struck dumb over a meal. Very odd, misogynist, almost freakish attitude.
The World Health Organisation recommends that children are BFed for a minimum of 2 years. Every child, from the richest nation to the poorest. So many countries in the world would think it utterly bizarre to not be BFing a 2 yr old!
