Query: Great for 1 month, terrible after that

This was great for baths for the first month when he would fit in the sling. Starting at 2 months old he was too big for the sling but the "seat" or whatever the bump is under the sling was completely useless for him. If we had the sling attached at the bottom his feet would get caught on the edge and his back sunk down into the bump. If we detached the bottom two straps of the sling then first of all it just got in the way and either he would lie with the bump in his back or he would be 90% out of the water with his head above the headrest.
