I put clicky box.
Reason being, I think it depends a LOT on if we are going to talk about military.
Where I grew up, where I had Damian, where I still have family, it was the dads... big time.
A lot of the non-military folk around here are that way... the husbands are with the wives carseat shopping.
but the military wives... even if their hubbies are around... unless it's their first time AND hubby is there AND they are dragging him around... maybe because hubby is gone so much.... it's the moms.
up where my ILs live... it tends to be more like where I grew up... except for my ILs, their kids (but they were raised military), and my niece (only one of the grand kids to have kids yet)... because she was raised to believe women should be independent and it was part of transporting the kids primarily, caring for the kids primarily, aka... part of primary caregiver.
but her hubby is also in school AND working, so that may add to it.
I don't usually understand the concept of "getting my husband" to choose the carseat, buy the carseat, and/or install the carseat, unless he's the primary caregiver.
I don't get why the woman wouldn't just try to do it and/or do it herself.
Now if she KNOWS her husband is better at it... or she's tried and not been able to exert the force needed to compress the vehicle seat adequetly, then hey... go to it.
But when you have little Billy or Betty in an infant seat that is outgrown because Daddy hasn't had a chance to put the carseat in yet, it makes me want to SCREAM!!
