One thing , for sure , as you will have known from trips to España , is that the Spanish LOVE kids ... Their little princes and princesses . Also, in the last few years smoking is banned in bars so your son will not be exposed to cigarette/cigar smoke . Some bars have ignored this rule but they seem few and far between . My brother has 3 daughters and a son in Russia . His son is about 20 months old now but he travelled regularly with all of them as babies with no problems at all . Quite the contrary ... as his 3 daughters are 100% travel and airport savvy now having been exposed to the travel almost from birth !
