"Mum Mum"

Logan finally said "Mum Mum" today, I had said to Brian the other day, "watch Logan will say Mom on my birthday" (which is today, July 13). I am not sure he meant "Mum" to me or just saying it, Brian thinks he was calling me. A few months ago he was experimenting with the Mum sound, but it wasn't connected with me, but it was neat to hear more than me being called "Daddy" today.
