Laboring in the Tub with an IV
Here is an option for laboring in the tub with an IV or Saline/Hep lock if the tub has a bar like the one in the photo
For this to work, be sure to check which end of the tub has the faucet BEFORE the IV lock is placed.
The laboring mom can then ask for it to be on the arm that will be on the side of the tub with the bar.
