My son was born in April and we never did an announcement card. We moved last year around Christmas when I was pregnant and right now I dont even know if I did cards last year (wow I really cant remember) anyway I am sending out cards this year with pictures of the kids. Should I put something like

love dh, me, dd and introducing ds
(even though he will be almost 9 months old, unless on fb no one has seen him)

or just list everyone and let it be they can figure it out themselves
