Hi K, that's normal. The kids protect the one that they feel is more vulnerable and -excuse my word- weak. My kids did the same when I was a mess and they were only 6 & 5. I think it's something they do without thiking about it, instictively (sp?).
So, the best way to get your kids out of this awkward position is to make sure they see and feel you strong and happy again. How is that for a motive? (another one) Love K
PS How is the singing, drawing,writing going? (did you notice you are now "The writer who sings"?)
