Hi B.,
My 2 1/2 year old has had tubes for about 1 year. She had a horrible infection a few months ago so I started the drops and it didn't seem to help. Tons of drainage and the ENT actually prescribed a longer, stronger dose of antibiotics. After about 7 days it cleared up, but it was a ton of drainage like you described.
As far as the water goes...The ENT said at this age not to worry about swimming and so far it hasn't seemed to bother her. I have never used the ear plugs. In the bathtub, I put a little vaseline on a cotton ball and put it in her ear to keep most of the water out. Also, if you kinda fold the ear over when you rinse out his hair, that helps.
