OMG thrilled that is so awful she had absolutely no right to do that.

My mum told me that my Nanna (her MIL) did that to her once, took me away from mum and wouldn't give me back, with both mum and I crying. As a baby apparently I never let her hold me again without screaming, and have never had a close relationship with her. Willow may be the same, she'll learn that she doesn't want to be around your MIL and there won't be a lot she can do to change that.

I hope you both have recovered from the stress of it all xxx
