I don't think the issue will be "what can I give the kiddies" it will be what the kiddies will be trying to sell you. We were there in March and we had our hands full fending off the vendors. We have been to Ensenada several times and it's all ways the same. Still it's a fun place to be. Enjoy the time while you are there.
P.S. That is a nice justure. I believe in a giving heart.
