Why are some babies so smiley(happy) and some are so grumpy

Could it be what we eat in our pregnancy and how we are emotionally that makes an effect on the baby. I've always had grumpy babies, they never smile, so hard to please.

Just want to hear about your experiences and how your diet was in pregnancy and your moods etc.

Both my pregnancies I was sick the whole way through. 1st preganancy I was very emotional cried alot. Second pregnancy I was so angry.
