I, too, have a 4 month old son, and we hope to move to Chengdu in August. My husband is an English teacher, so he’s still looking for jobs right now, but Chengdu is where we’re hoping to move. We won’t need formula or diapers (breastfed & cloth diapered) but I have been wondering how the vaccinations go overseas.
I imagine that it’d be nice to know someone else with a baby of the same age, so maybe we can keep in contact!
Oh, and there seems to be a pretty active Women’s expat society in Chengdu: http://www.chengduiwc.com/ That has some good info & links on there too. 🙂
