They've explained all this, Gaara wasn't loved by anyone as a child. This was the central theme of Gaara's existence and they drilled it into the viewers' heads even up till these past shippuuden eps. The love tattoo was created by Gaara himself in the flashback where he kills his uncle, along with the realization he makes that only he will ever love himself. The mother has nothing to do with any passive sand shield.
