I put once a month. It use to be so much more. When we first got Katie I just couldn't stop myself...lol. NOw that Tori is here they seem to keep each other entertained so I don't buy as many. I actually haven't had to buy anyting lately because Anna, Kay and Amy have kept us well supplied with bandanas, treats and toys I put them up and rotate them so they don't get so tore up.
