Today's post-Parenting

It made me so sad that I was at work today when my son decided to take something from his little sister today. Let me clarify, he's almost 4 yrs. and she's 7 mos. My mom was there babysitting and she handled it just fine, but I wish I could be there for those moments and be the one to explain to him that his little sister is too little to understand sharing. It's such a little thing, but I really wish I was there to handle this situation. I want to be a stay at home mom.........;-(
