lol!!! My AprilLove squeeks hers (and every other squeeky toy) non stop sometimes, I have become immune to it!!
It's to the point now that the sound isn't deafening anymore, it is just part of a normal days sounds at my house. She especially likes to do it when I am on the phone, she'll climb up at me and sit on my lap and squeek squeek until I throw it for her, then repeat
I don't give her any time limit, I figure if it makes her happy, then she can squeek to her hearts content hehe
