Oh dear, I know it's tough, but you have to bear with the situation. I was once in your shoe but things only got worst when I was trying to push my hubby to settle down on our own. My mother in law never carried my gal before...we stayed in the same house (in Phil before) but never once she asked me what happened to my kid everytime she cried.
It's better to be independent than to seek your mother in law's help. If she will have interest to carry you gal, let her do so...if she doesn't then dont't feel bad about it. dont't expect so that you won't feel hurt.
