Ian can now say please. Actually, he says it without using vowels, so it’s more like “plsss”, but he says it and uses it correctly as in “more plsss” and “ahnuh plsss” which means again please. The again please comes in very handy while we are watching “This Hat” for the eight billionth time.
Claudia doesn’t say please, but she does say thank you. She uses it often. She almost always says it when you give her something she wants (as long as it is not the result of a tantrum, then the fact that she has stopped screaming is thanks enough), but she also generally says thank you when she gives you something. It’s not perfect, but it’s a pretty good start.
