Sharing is something that you want to encourage. I think it's great that my 29 month old wants to share with her 7 month old little sister.
The problem is what she wants to share with her. BLS is one thing, but being given a toasted multigrain bagel with butter is quite another! It's not like we're leaving them unattended, but as any Mom can attest to, 2 year olds are freakishly fast.
For Mom's with babes close in age, how did you stop them from sharing inappropriate foods?
