Oh now as they opened the gate for all Aam-bloggers, I could see the topic.
"How important it is for children to catch up on lost growth" is strictly a topic which should be dealt either by a health counselor, nutritionist or a pediatrician. Everything can't be googled and assimilated. Otherwise we won't be needing professionals.
How much should be the ideal weight for age, height for age, Calorie requirement per day etc are topics which demand knowledge of respective professionals. So, I'll stop whining for voucher opportunity under this HH and choose blogging ethics here. Everyone is free to act by his opinion. Best of luck and cheers to fellow bloggers who would or wouldn't participate in this HH.
