Mine doesn't eat her feet. But she had been playing with them the last couple months
My second plays with her feet but only her hands go in her mouth. My first basically went from insisting on being in my arms to crawling so he didn't really have a chance to do this.
Moth baby do this
Mine is 7 months and still loves eating them! 😁
That's actually a milestone
Both my girls did this when they were around that age. Completely normal, it's their way of exploring their surroundings ☺️
