I want to purchase an item that says suitable from birth to 9kg, assuming you have the ‘average’ child, how old approx will the child be when it reaches 9kg?
My daughter was 9kg at 6 months. But anywhere from 6-12 months is about average.
I am looking into my baby health book and it said
For girl : average weight will be 10th month
For boy: average weight will be 9th month
But if the baby iis fatter than avergae
For girl : at 7th month she can be 9kg
For boy: at 5th month he can be 9kg
about 6 months seems like a good guess. most clothes are 0/3 months or 0/6 months for new babies
