Will u buy a convertible car seat for your twins who are not walking yet??

Myia • 28 year old first time Mommy with twin boys born Nov 14th 2016..mommy so in love with Mekhi & Malik❤❤❤❤
My twins will be 11 months on the 14th and they are just under 18lbs..I have not switched over to the convertible carseat yet because they are not walking and I think it will be very difficult to get them n and out the car without the infant car seat..is anyone else waiting till the twins can walk until switching over ???
