S.H.
with one of the boys in my daycare, since age 18 months, he's been militantly saying, "TIME-OUT"....& pointing his finger like a gun! I don't do it, but he certainly does! He started doing it at home over a weekend (& they rarely use time-out!)....came in on Monday doing it & it's just been toooo funny!
Mom & I have talked about it, laughed about it.....& that's about all we've done. Neither of us are concerned, both of us realize that we are humans & can make mistakes/slips/errors. The same child also yells, "shut up" to my dogs & the neighbors' dogs! That phrase Mom does claim...because she said the whole family yells at their dogs.....thank goodness it wasn't me!
Kids can be crazy with their mimicing.....I think the tone of voice is more the issue than the actual words.
