Tips on gaining weight after baby.

Mirian • Momma of 3 💙💙💜
Anyone had any problems with weight loss after having baby? Have any tips on gaining or not loosing too much weight? After my first son I lost alot of weight & couldn't seem to gain any (especially since I was breastfeeding for 6months.) I hated it because I looked way too skinny & didn't feel good about my body. So this time around I've been trying to figure out what I can do to gain weight or atleast not loose alot of weight. I'm 3 weeks postpartum with my second & currently breastfeeding. Anyone have any tips??
