We have done both public ferry and private- GB ferry. Paperwork entering/ preparing to enter Anguilla is just about the same for both ferries.We were told GB was quicker (because of paperwork) but it really isn't. GB is great and will pick you up at the airport to take you to their boat. They are very friendly. Sadly we had to wait for other passengers, almost an hour before we could leave for Anguilla. The public ferry runs on schedule and is very easy. You park in Marigot or take a taxi up. In Marigot you pay the departure tax($5), get your boarding pass, have your passport checked once more, then wait for the ferry. You pay $20/person cash on board, not sure about babies. Coming back you pay the fee at the counter $20/person, go to the next window for departure tax (over nighters are $23, not sure about day trippers). I wouldn't hesitate to travel with a young child on the boat. As someone who is cautious on the water, it is basically the same ride. With the new bridge the trip to marigot is pretty quick. A ferry trip of 20 min or so and you are in Anguilla!

As a return viistor to Anguilla (many day trips) with a young child I would suggest just going by taxi. The driver will give you a quick tour of the island but with a little one you are probably best doing one beach. (My kids didn't like a lot of transitions!) on Shoal Bay East you can eat, drink, be merry, take turns snorkeling and is very relaxing. I am not sure which other beaches will offer snorkeling.
