My LB had teeth at 3 months old so couldn't hold onto things well! Bought this as I thought it might stay in his mouth without holding it but the 'teat' part was too big for his mouth and I had to hold it in his mouth anyway!
Great seat for babies who can hold up their heads but not their bodies yet! It really supports them well! The only thing with mine is once I popped the tray onto the stand part I can't get it apart again so getting the tray onto the bumbo is a bit if a fiddle when baby is in it but it's not so bad that I won't use it! It's used everyday!
