During my 1st pregnancy with DS i didn't have any morning sickness and gained 20kg by the end, at least half of that was in the 1st Tri. Looking back i think i was so excited about being pregnant and use that as a reason to just eat everything After DS was born 10kg came off pretty easily with breastfeeding, but although I tried I couldn't budge the last 10kg.

This time round I had morning sickness until week 10. So at this stage (21weeks) I am still below what I weighed pre-preganancy, I think also running around after a 2YO i just haven't had the time for naughty snacks.

I think my OB's recommendation was up to 12kg's, but that said as long as you are healthy and bub's is healthy that's what counts.
