"Cinco, Dos"

"Cinco, dos." This is Gabriella's newest "phrase!" She says is at random times and I don't believe she is "counting" anything. She roughly understands counting in Spanish up to seis / six. I will say, "uno," she'll say, "dos," etc. up to seis. So I believe she knows that cinco, dos isn't proper order. Sometimes she'll even add an extra "cinco" or two (or more) to make it "cinco, cinco, dos, etc." Maybe 52 is her "lucky" number? Very curious!
