Is it a shared hot tub? I don't tink it would be very nice for other / subsequent users to follow a baby in a soggy swim nappy into a hot tub. Put her by the side in her bouncer or car seat or something?
It would depend - if it's a hot tub for your room and you can set the temp then yes if you keep it cooler, but if it's a hot communal one then no, they can't regulate their temperature, so its not good for them.
I would still take your swimsuit though because you never know who else will be there who would love to sit by the pool having a cuddle while you soak - win/win Also you might be able to take the buggy near by and go in when the baby is napping.
I am LOLing again at the heights of indignation and extremes that thread achieves It should be a Mn Classic, for it's speedy recourse to toddler death and the breakdown of civilisation as we know it, and all over a jaccuzzi.
It's a private hot tub, not a hotel/spa. So I'll check out the chemicals and temperature issues when we get there, and only take her in if it is clean and cool enough. She loves water, so I don't want her to miss out if it is safe.
I have a theory that people flock to hot tubs on holiday or have them in their gardens because they shag in them - therefore I will never go in a hot tub unless it is at the gym as I know no one will be able to shag in that one as has a camera trained on it all of the time!
But to the OP - no do not take your child into a hot tub - it is very very dangerous, hot tubs are HOT, TOO HOT for a baby and you could cause brain damage or death by putting her in it.
