It is very hard to show pain or hurt to your child. I think it is almost an instinct to protect them, to be strong for them. You think if your child sees your pain they may be scared or hurt, and you just want to protect them from that. I had never even thought that this may not be the best thing for my children, as your mother probably did not. Maybe if you tell your mother how you feel it may help, but please remember the need to protect is strong.
