Kids store filtration

I've been working on a parent app redesign recently and it includes an e-commerce section for the parent to buy clothes or stationery for his children.
the old design contained gender and all possible ages for children from months to 13 years, the challenge was to come up with a solution more friendly with the user and more simple.
so, instead of listing all ages and causing conflict, the solution was to replace it with a filtration option that automatically shows up if the parent clicks on the gender.

your feedbacks are highly appreciated
