I am short and pre baby was around 60 -65 kgs - with DD I put on 15kgs and with DS I put on 20 kgs. Don't forget that that is also baby (4.560kgs of baby for DS!!) and then fluid etc. I lost all my baby weigh within 2 weeks of having mine although everything seemed to change position on my body!

It sounds to me like a normal gain, but if you are worried I guess all you can do is make sure you eating healthy, sensible food most of the time ( i say most because I craved maccas and nothing was keeping me from those golden arches while pg). xoxox
