we can use actual molds you have if you can guarantee that the angle is the one we want
for the seat
position
the baby belt you should make it adjustable
that can be adjust for heigh and weight wide and tall
the base of the stroller could be yours if youc an put the seat as per our requirements witht he belt or sling on top as per we want
do you do the test with real baby on how to use it???
