My oldest LO almost never put anything in her mouth, so when I had LO2 and realized she puts EVERYTHING in her mouth, it kind of made me anxious. She's going on 2 and anything with small pieces is on the top shelf of the closet. I'm really paranoid about it, but hoping she will grow out of it soon. Was there a magic age where your LO just stopped putting things in their mouth? Even bigger things...
