RE: Would you go to Mexico with an infant?
I just got back from spending two weeks in Tampico, Mexico (actually Altamira, but it's close to Tampico) with my 8 month old. Obviously, he's a little older than your baby, but I would still go in your shoes. Especially if y'all are staying in a resort. Conditions there will probably be very nice, and you will only need to take a few basic precautions (use bottled water, don't eat food from street vendors, etc). Especially since you're breastfeeding, I don't see a problem. I would, however, bring a couple cans of formula just so that, in the rare event that you got sick and dehydrated, you would have something to feed the baby and not have to go looking for formula.
May I ask where you're going? I've been all over Mexico (I was a translator before DS was born), so I might have some tips on the exact location.
Oh, and if it's any comfort to you, we chose a delayed and selective vaccination schedule, so DS had actually only had his first Hib, IPV, and DTaP vaccines when we went. My ped wasn't concerned, and neither was I. Avery had a wonderful time, and I really enjoyed the trip.
We had to get DS's passport expedited, and there weren't any problems...we had it in plenty of time.
HTH! Feel free to PM me if you have any other questions.

The biggest mistake I made is the one that most of us make...I did not live in the moment enough. I wish I had not been in such a hurry to get on to the next thing: dinner, bath, book bed. I wish I had treasured the doing a little more and the getting it done a little less. - Anna Quindlen
