It needs a stopper on both ends
My 7-month-old LOVES this and will chew on it for a long time. I really like the stopper so she can't gag on it. However, if she grabs it and puts the wrong end in her mouth, I find she can gag herself quickly because that end can go really far into her mouth. I have to watch her CONSTANTLY while she's chewing on this or she'll have it turned around and gagging on it in no time.
