I have a friend's birthday coming up and we're going to a spa for the day. I understand it would not be advisable to use the sauna/steam room but I don't see why it's not wise to use a jacuzzi. The ones I've used before have been a nice warm bath temperature, possibly slightly cooler than the baths I have so I don't see the risk of overheating. Am I missing something? (This is baby no 3 for me so I'm a bit more relaxed about everything!)
