Any advice will do...

Hi,

I had my daughter 2yrs ago she was born preemie at 32 weeks only weighing 2lbs. Long story short she's 2yrs old and only weighs 19lbs we have been battling with her weight gain and the fact that she's having problems with her iron level. Her level is so low that it is in the single digits and the doctor said it could start affecting her oxygen 😓. I've recently stopped breastfeeding her for bout a week now and I'm hoping and praying that will help her want to eat more table foods. Any suggestions on what will help her gain weight??
