Brought my LO for baby spa, she was really cranky at night. Is she too excited from it?

Cranky means overtired baby. You should always ensure that she had her nap before her swim. She shouldn't be swimming more than 15-20 minutes and after which, because this physical activity is tiring, bedtime should be shifted 30 minutes earlier. I bring my boy to babyspa and through many interactions with the mommies and staff, this info is commonly communicated to all parents. An overtired baby must be held constantly and will cry when you put her down.

Just like swimming, Babyspa should be quite relaxing, so I don't think it will make your baby too excited. In fact, I think alot of babies end up sleeping on the float because it is so comfortable. But different babies are different, maybe you can monitor your LO again if you go there a 2nd time.
