I figured some of the new dads here would get a kick out of this.

When we go grocery shopping we give our daughter, who is now 21 months old, a lemon to hold, a task she has been doing for some time now and quite well. Occasionally she gnawed at them a bit, nothing more then nibble the nub off. Well currently she must have a molar coming in as today she ate through the skin and some of the flesh. The tang of the lemon not bothering her.
Weird kid, must get it from her father :-)
