I really don't know how it works....But I dont' think that eating too much is going to make the baby bigger or eating not enough will make the baby smaller, however either way could make the baby unhealthy.

As far as my baby is concerned I want a decent size baby and I don't, at this point, care what my baby weighs. As long as she is healthy. She is going to need her mommy and nothing is going to change that. (it doesn't matter if she comes out walking or not.)

Its genetics...

My friend was 11pound 4 ounces ( oh an the mother gave birth to him talk about ouch!!! ) haha

i was 5pounds 11 ounces.. My birthmother was tiny! She was 4'11-5'0... Its a good thing she had a little baby! (lol )

Big babies run in my family but we gradually got smaller, my grandma was 14lbs, my uncle 10lb 10oz, my mum 9lb 6oz, then I was 8lb 4oz my sis was 7lb 2 oz , my daughter was 7lb 4oz and my son was 7lb 7oz. I don't really know if genetics does play apart. It could be to do with the pregancy too.
