My 4yo has always been skinny but BMI dropped to the 9th centile from the 60's. HV told me to give lots of high calorie foods which I did, she gained and went up to 52nd centile. I was told she's fine not to worry her weight is fine but 4 months later she's back down to 20th centile.
I can see all of her ribs, she looks notably skinnier than the other girls as dance.
Should I be concerned as technically she falls under the healthy weight bracket it's just she's falling down the chart BMI wise.
