If for legal purposes there is no INFANT as of yet, who could "Your daughter" be? They are making a claim. The burden of proof is on them.
And who are YOU to reply to such notice IF you have no INFANT, as of yet? :D
RETURN TO SENDER. NO CONTRACT. NO SUCH INFANT.
Who is it being addressed in the envelope? Does the envelope has a clear window?
