Yes i have a bath seat
We usually advise after 24 hours old, plain water for the first few weeks. They lose body heat quickly in the first 24 hours. Cords are fine to get wet, just need to make sure they’re dried before getting baby dressed again
I left it till his cord came off as that's what was said in my antenatal class. Then they said after that max of 2 a week and short periods of time as they get cold. Then when they're abit older can bath them more. I wash him top and tail every day as part of our routine. Nothing in the bath like toiletries until after 6 weeks.
When their cord falls off. Have you got a bath seat ?
