I liked 2 bathtubs for my son. The first is the white one pictured above. It is very large, so it worked for a long time until my son was big enough to be in the big bathtub by himself. It is called the "Eurobath."
But...when he was really little I didn't love using the kitchen sink like some people, so I had another bathtub that is great too. The "Sure Comfort Deluxe Newborn to Toddler Tub." Now that is a mouthful. I loved how it has a sling to cradle the baby so they aren't lying on the hard plastic when they are so little. It worked very well, but then he just got too cramped, but wasn't old enough to sit up in the big bathtub, so I needed the Eurobath too.
What did you do? Do you have any better options/suggestions? I would love to hear them!
