Confused

Ok, so my baby was born 21st December 2018, weighing 7lbs 1 oz.

Yesterday I had my health visitor out for the 6 week check up.

Baby girl is weighing 9lbs 11oz at 6 weeks.

My health visitor was making me really worried about her weight but wouldn’t tell me if it wasn’t bad or not but kept pointing it out and her growth graph.

Is there something wrong with her growth? Should she be bigger or smaller? I’m confused.

Also, how many oz of formula were your 6 week olds drinking? My babygirl has just started 6oz feeds on hungry baby formula😱 Health visitor didn’t seem worried about how much she was drinking.
