Moms of twins:
What car seats do you have? Do you like them? I have spent hours researching and still feeling completely overwhelmed. All I know is I priority 1 is safety and priority 2 is lighter weight so I can physically carry both.
The only seat I've seen specifically reviewed for twins is:
Maxi-Cosi Mico Max 30 Infant Car Seat. It looks great - but I'd like to comparison shop.
