Lost to much weight??

Barbara • My daughter is my everything, my family is what I live for ❤️ ][life`s not about Creating yourself !
So my dilemma isn't your average compliant, i just had my daughter 16days ago td. And before i was pregnant i was waaay to skinny 100-110pounds thats it. While i was pregnant i only got up to 137, so i had my baby girl and im already at 116_ i wanted to be and stay at 120 the Least. I need to figure out a way to get weight on and KEEP IT ON!!! I look like a skeleton 😣😔😞
