No money?

Ruby has gotten to the stage where many of the things she says have a meaning (instead of just babbling). We understand a fair amount because most of her words are ones we’ve worked to teach her. Here are some newish words she knows and says:

• car
• truck
• bicycle
• thank you
• bow wow (for dog)
• sock
• shoe
• hat

Recently, though, she has started saying a word and we can’t figure out what it is. It sounds just like “no money”. Sometimes she just says “money”. It seems to be in context when she’s having her diaper or clothes changed, but I can’t think of what word(s) she means!
