This morning Billy was voicing his displeasure at some injustice (real or imagined, I can't remember. It may have been that breakfast wasn't on the table yet!). I turned to him and said "What's the matter kiddo? You are just a yeller aren't you? You're my Old Yeller!" (he probably didn't get the old cinema reference, but I was amused) Erin looked up and said "Yes Billy, you are OLD Yeller, soon we will have a NEW Yeller, the new yeller is in Mummy's tummy!!"
Somehow I think she has a realistic view of her younger siblings ROFL
