Allowed 20lbs

Aly • I'm a 27yr old graphic designer from Southern Indiana just living the family life with my husband, daughter, and dogs! Expecting our second 12/16/16!
At my last apt my dr told me he wants me to gain no more and no less than 20lbs. That doesn't seem like much to me! I only gained 31lbs with my last baby (shes 1) and have lost all but about 5lbs. Anyone have tips on how to manage or spread the gain when I have to eat every 2hrs to keep the nausea at bay?
