When I can't find something I'm looking for, Sara says

"Don't worry mum.  I'll get it for you next time I go shopping. OK mum?"

When I'm lamenting the fact that something is broken, Sara says 

"Don't worry mum, I'll fix it for you later.  OK mum?"

When I tell her I'm not feeling well, Sara says

"Don't worry mum. I'll make you feel better." She pretends she has a fairy wand, waves it about and says "Turn mummy all better!" Then she asks "OK mum, OK?"
