We've purchased our infant car seat already, and I purchased a convertible car seat this morning from NBD (yes, I am insane--but I can't resist a good deal!). I will be taking 5-6 months off for my maternity leave, so during that time I'll be using our bigger SUV with the infant base installed. Our plan is to install the convertible in our other (smaller) SUV from the get-go and not get another infant base.

The smaller SUV will primarily be used for daycare pickups/dropoffs (my DH will drop off and I will pick up or vice versa) and she won't be going to daycare until around 6 months old.

I just don't see the need to spend $80 on another base if she'll rarely be in that car. Does this sound like a good plan? Did anyone do something similar to this?
