Hi, Swoop,

Having a sick child is going to be the thing that undermines the confidence of even the most confident mother. But you have to know that you did not cause this situation - but that you are responding to your little one's needs in the most loving and attuned way. Children with allergies and intolerances are high needs kids. They are often slow to gain weight - and there is a high correlation between reflux and allergies - they are on the same spectrum. The good news is that largely children will grow out of these things. Allergies and intolerances are partly due to genetics (you can't do anything about that) and partly due to environmental factors we don't yet understand (can't do anything about that either)
My best advice - don't make it into a food fight. Help guide your little one - model my eating the same food as you are giving her. Keep meals fun and social. You are doing a great job with her
