I put on 25.5 kgs with my first baby and at the time i didn't have a car so i walked evrywhere. But with my second i put on only 8 kilos and i didnt really exercise.
I lost the 20kgs after josh within a month.

It depends on our size before too. i was underwieht when fell pregnant (only 45kgs AND I'M 172CMS) so the doctor said id put alot on cause i needed the extra weight anyway.
