We traveled to Hua Hin with our four month old son. The hotel provided a crib. The room was large and the bed comfortable (Note: we both prefer a bed on the soft side. This was what I would consider medium. Everyone has their own bed softness preference. I find that beds in Thailand tend to be hard so, if you prefer a hard bed, this will probably be a bit too soft for you). We had a balcony with a daybed and, perhaps the greatest design feature I've ever encountered in a hotel, towel racks for drying swimsuits and beach towels. The bathroom featured a rainhead shower, as well as a handheld one, and the hotel provided towels for both the shower and the pool/beach, which was convenient.
The pool area was large with a lot of sun loungers, a handful of which rest in the water, which was perfect with the baby. The pool also has a large kids section, which was slightly too deep for our 4 month old but is the perfect size for mobile small people. There is also a large 'grass' area for kids to run around if they wish. The pool has a bar area, though we didn't use it so I don't know how good the food is.
The hotel is a bit out of the center of town (about a half hour walk) and the public beach but they offer a shuttle for a small fee. We found the fee to be almost the same as taking a Grab (the local version of Uber).
