I miss my prenancy time even I have ms but not so serious. The feeling is great. I still remember I gain 1 kg per month at 1st trimester until enter 27 weeks my weight start to gain 1.5 kg per month.
Before pregnant 56kg and at week 39 is about 70kg.
Isaac is 6 months and since give birth I start loss weight.
Now my weight is lesser than before pregnant. 54kg
So, new mummies please remember to eat small portion and at least 5-6times per day.
It won't not really gain so fast but you still can fulfill your craving.
