SandraLesly,
Have you ever tried just giving her the pill? Nolan who is now almost 11 months just takes the pill in his mouth. He has for quite a few months now. Jackson is the same way. She may not want food but she may not have a problem chewing the pill up.
As far as not gaining weight...my friend’s daughter had that problem and her doctor told her to try pediasure ( I think). It’s the shake for kids who need to gain weight. She might like that.
Talk to you soon,
Sandra
