N.K.
In all honesty I would skip the infant seat and go with a convertible like the graco Myride that way you can keep them rear facing for so much longer (now recommended to at least 2 yrs old) I know that it is easier to have the infant seat to take in and out but try a sling or wrap then you have both hands free to chase the other to kiddos. Safety is the most important over convenience. So Rear face as long as possible
