I have always thought the TummyTub was a great idea but I am now using it with my 4 week old granddaughter Olive and she loves it! Because it is so portable it can be used anywhere in the house and if you use it on the floor you can get really close to the baby. This both reasures her and gives the parent the confidence to let go and let baby just float. Also having it on the floor makes it so easy to scoop out the baby and wrap her in a towel. Bathtime is now fun for everyone!
