My daughter is 5.5 months old and well into the phase of "everything I can get my hands on goes DIRECTLY in my mouth". She's not teething, just exploring her world via her mouth. I know this is totally normal, just wondering at what age it stops. It terrifies me to think about the number of germs she's putting in her mouth. Her day care is really great about keeping the toys clean and all the babies get their hands washed every time they get their diaper changed (at least every two hours) and we try our best to keep things clean at home too... but you can only do so much!
