Not taking mother's advice

My mom is angry with me because I appearently don't take her advice. I'd say I do maybe a third of the time. She has only spent time with my son 4 times, and I have spent every second of 2 and a half months with him. My son has bad reflux, he hiccups multiple times a day, spits up a lot of milk and coughs. Yesterday my mom said "I took my mom's advice and my kids never got sick, never cried and never had acid reflux". My response, "Oh, so it's my fault he has acid reflux?".

I am still so mad she said that. I am hurt too. She never says I am doing a good job even though my son is very happy and healthy. I love my mom, but right now I don't like her. She is very hard to talk to and just got out of the hospital for the third time for suicide attempts.

Would you be mad at that comment?
