12 week old in Mexico??

Darkry

So I wasn't really sure where to post this but settled here.

We were invited to go with my SIL to Mexico for 4 days for new year's. We live in Arizona and she lives on the border and goes all the time, she also has 3 kids. We would be driving over the border. I was just wondering if anyone had any suggestions or thoughts on the matter. My son will be 12 weeks old at the time and I haven't traveled anywhere with him yet.

Pic just because 😛
