My 10 month old girl swallowed a small plastic shirt button. My 4 year old was playing with buttons on the table and i was so careful there isnt any on the floor but the minute i turn i see a button in her mouth i try to pull it out from her mouth and she swallowed it didnt even choke on it. She pooped after 2hrs of swallowing it and i dont see any button! IM freaking out!Do i take her to the ER?She doesnt seem uncomfortable or anything.
