Should I accept money from my mother-in-law?

I am a married man with a beautiful wife and a one year old baby. I recently lost my job without prior notification. I have very little savings to fall back on but my mother-in-law who is very rich says she would be sending me money for my family upkeep. I expected her to give money to her daughter but she's insisting on giving it to me. Should I accept the offer or not, knowing fully well how women can be when they start giving you small change?
