Re: Normal Toddler behavior?
Lol, I think it's normal. My 2yo is scared of "honk honks" (fire/smoke detector). Ours went off once because the battery was low. It was interesting trying to get her down the hall to her room for a few weeks.
On the other hand, my 11mo think all loud things like the vacuum or coffee grinder are great, and belly laughs at them.
