We have an official first word!
For weeks we've had something sounding like Daddy, something like Mummy and a Doodah sounding word for milk but none consistent enough to say for definite.
Last night in bed I said to Anna Kisses and she repeated Kusses. I wasn't sure so I said Kiss and she replied Kuss. We tried twice more and got 4 definite Kusses. I'm not sure the wee besom will oblige by repeating it again today but last night we definitely had a first word.
