soy sauce anyone?

I was lucky enough to hang out with a fun mom today and she told me about something she did that I think is brilliant! Her son was past the 1 year mark and still wanted to nurse all the time, he would claw at her and she was sick of it. So she applied some soy sauce before she nursed him (of course he had no idea). He was really confused why it tasted so salty and decided he didn't like it and stopped nursing from then on! Maybe this is a practice that is well known, but I haven't heard of it and I think it's super great. She told me when she had her baby #2, her son asked if the new baby liked salty milk (she told him yes). Kids are hilarious and adaptable and moms are so smart!
