X-Mas Gift Advice for soon to be porker nieces. Last weekend I was invited to a family lunch, and I disgustingly noticed just how chubby my two nieces were getting.  They are aged 8 and 5 and they use to be normal. What sort of Christmas gift does a concerned uncle buy to shirtlord his nieces back onto the plantation?  The father is not the main (he is normal BMI) problem, its the obeast mother that allows them to gorge on sweets whenever they want all bloody day. I have no idea how to positively motivate them, and it's not like its the children's fault.  I don't want to be mean about it either over Christmas either. I have only been able to come up with vouchers to ballet / dancing studios, as hopefully seeing fit healthy girls around would get them to start thinking.  Though the parents will probably just throw the vouchers away because it might interfere with their busy lives. I am open to suggestions. Thanks for the all the replies everyone.  I will take it all into consideration.
