A bit petty but here goes.
DS is 14 months.
Has good oro-motor development
Has a handful of words, mum, dad, woof, hiya, more, milk, hi 5, bye.
He is very communicative and playful.
MIL keeps encouraging him to blow raspberries. He can do these easily and loudly. They sound very trump like!!
I'd rather not encourage it but it's become her party trick with him and she kind of shows off!
Would you say anything? I think it will get less cute as he gets older.
