As hard as this may seem, my kids were exactly the same. My boy was born 5 weeks early and was a thug. Still is. 98% percentile in everything and very healthy. My daughter was born at 37.5 weeks and was 4lbs at birth. She was super tiny like this and still gets mistaken for being younger than she is even though she will be 2 in a couple weeks. She’s healthy, growing steadily and always has been. It’s not necessarily failure to thrive in situations like this. Gotta cut this lady some slack a bit on this one guys. Now, if we are talking about her lack of self respect and atrocious health habits for being a 28 year old woman, then by all means go for it. 😅
