Other parents say, “I knw it is wrng, but it’s quicker t d it by myself.” Getting children t d sme husewrk is a ver big prblem in these families. As a result, children frm these families hate t d chres even if they grw up.
Peple find that children as yung as 18 mnths can help with chres. When parents say t thse children, “Culd yu 4 (pick) up the paper?” They will pick it up.
