Hi Booga,
I've just returned from a dive vacation in Cozumel. The trip was fantastic! I hope you, your SO (significant other) & sprog can go there soon.
I thought you might like some information on how childcare was arranged:
There were 4 children on this trip. 2 boys, 18 mo. & 4 years old, and 2 girls, 11 & 13. The two girls were a big help with the children. The girls loved playing with the boys. The children were very good travelers too and they all loved the water. During our SI everyone went snorkling (except the 18mo, his mom just swam around with him). The first 2 days of diving we had everyone on the boat. It worked well except the girls got bored and after the 2nd day their parents hired a babysitter. $50.00 USD for the whole day up to six children. The sitter was really good - everyone liked her.
The hotel we stayed at (Park Royal) had a kids play area with a kiddie pool & slide. The kids & sitter hung out there while we went diving.
The 18mo old did delay his mom's diving because he kept wanting to nurse when she started gearing up. Her husband is the one who found the sitter. The 18 mo's mom never missed a dive - in fact she dove from shore before we went out on the boat 3 mornings in a row. Her husband is very supportive and took care of the kids.
I think the key with these kids is that their parents have stayed very active and the kids are used to traveling.
I hope your pregnancy is going well!
