Right now my carseats are like this, Dakota in a radian, Kaleb in a graco gargo and Colton in a FPSVD. Now my questions...Colton still fits in his SS1(he only weighs 18lbs), but i got him a FPSVD before they quit making them. Kaleb has only 4lbs before he outgrows the cargo and then he was to go into the radian. But Dakota is no where near ready for a booster. Kaleb still fits in the FPSVD, he would be using the next to top slots, so i was thinking...put Colton back in his SS1, Kaleb in the FPSVD and leave Daokta in the radian. However i have the opportunity to be able to get another FPSVD for Kaleb. SO WWYD, put Colton back in his SS1 and give the FPSVD to Kaleb or leave Colton in the FPSVD and just get a new one for Kaleb? I am leaning toward just getting another FPSVD.
