I gave my kid few nuts which had badam, cashew and pista. the pista was with shell but I didn't count how many were there. After she ate I saw she didn't eat badam and left only one pista with shell. I went busy with other work when she was eating so I missing to notice her. but I had doubt if she could have swallowed any shell ! Suddenly after 2 hours she vomited. Now I'm worried. pls guide.
