Ok, first YOU ARE NOT A BAD MOM! Learn from this... YOU make the rules for your child, YOU know what he needs an dwhen he needs it! Your mother is not to dictate what you know your child needs. I would have asked her to leave! I am totally serious! She first off should not have put her hand on his mouth, that amplifies the problem! He was obviously getting frustrated reading and needed a break! She does not understand any of this yet. If you can find a workshop that you and her can go to, I HIGHLY suggest taking her to it. I made it clear to my family and inlaws at the time that I make the decisions regarding my children, then when Logan came along with all his SPD issues I became even more strict about my kids. If you do not understand the issue stay the hell away! You are not going to make my child's life miserable or ruin his day because of your ignorance! I'm sorry but there is nothing that upsets me more than people who want to ignore what is smacking them in the face! You are probably a much more reserved person than I am, and the next time you know he needs his chewy, your mom says no, you go get it give it to your son, have him go where he needs to go and take your mother off to the side and tell her; I am sorry that you won't take the time to understand your grandson's problem, but I do know what he needs to help him. (Sorry that is about as nice as I can get)You said she watches him for you, how does she deal with his meltdowns when you are not there? You are a great mom, you know your child, you knew what he needed, you had that one moment that I bet you will never let happen again. The next time put her in her place and she will eventually learn! I am sorry but that makes me mad, I know she is your mother, but it is just people in general, I see it all the time at work. I sub in a school dist and they have kids with SPD in behavioral classrooms and expect them to sit still nad not talk! I am actually going back to a school today that I subbed at and bringing them fidget toys that I bought for them! They are being punished for behaviors they CANNOT control! They will never feel successful if they do not get the help they need! One kid gets punished for having an outburst, but he then gets right back on task! He needs to hop all the way to the bathroom and he gets yelled at for not walking in the hall! I took him then and had him hop all the way there and back! Uneducated people teaching children with special needs who do NOT know how to handle them! EDUCATE EDUCATE EDUCATE! It is the only way we are ever going to change the way these SPD kids are viewed! Ok, sorry I will get off my soap box now! Have a great day!
