Is it true what they say about having a 2nd child?

Breyana

This will be my second pregnancy. I have a 5 year old daughter and I am 6 weeks pregnant. People say that once you have your 1st child, you tend to show quicker with your second. Is this true or a myth? Either I'm just gaining weight or my baby bump is coming in early. Any 2nd time or 3rd time mommy's out there than could elaborate.

Thanks
