Staying healthy in Central America?

I will be traveling to El Salvador in a months' time. I have gone before and got a little sick from the food and water. I tried to avoid it as much as possible but it still got to me. As far as eating, what's the best solution: shopping for a few items and cooking them myself, or eating in mainstream restaraunts(instead of the street vendors, and little "kitchens")? I will be on a tight budget, so I can't go to high end places.

Is there a way I can boost my immune system to survive the trip as healthily as possible, or vaccine, or supplement I can take? Also, I will be taking my nursing 7 month old along with me. I'm thinking keeping her on the breast the whole time will cut out as much exposure she gets to possible sickness? I will be there for a week.

I haven't been to El Salvador but I imagine it's basically the same as Mexico and my home country, the Philippines. Given the tight budget, I guess staying at the Hilton is out of the question. LOL

Seriously, I would suggest you splurge on bottled water and canned foods (or what you said, do your own cooking). You'll breeze through the one-week stay just fine...you'll be okay.

I'm more concerned about the baby. It's really a good idea to breastfeed her - just to be on the safe side. Just make sure that even before you leave, she's already used to breastmilk so the transformation would not be so sudden. And also, bring lots and lots of diapers......her skin may not take too kindly to the local brands (and the familiar brands maybe costly). And don't forget her usual colds meds (consult her pedia) - some babies don't adjust well with weather changes.

Re: something to boost your immune system...consult your family doc...I'm sure there's something out there for you...be sure to mention that you'd be nursing your baby.

Have a safe trip and have fun........God bless.
