LOL....too cute about the jumping in the water bowl. I am not sure how long teething lasts but Brodie is 6 months old and still teething. You just have to be firm with her about no biting and train her to stop otherwise it will continue on and get worse as she gets older because then it is a game. I recommend using coins in a can. It worked WONDERS for Brodie!!! When he acts up now all I have to say is you want me to get my can and stops what he is doing and lays down. LOL and I only had to shake it a few times now I just threaten to use it.
