Toni Collette pretends to be a monster to entertain her children.

The 40-year-old actress loves playing games with her kids - five-year-old daughter Arlo and two-year-old son Sage who she has with husband Dave Galafassi - and they like it best when she pretends to gobble them up.

She said: ''For the last couple of months, my kids have been big on me being a monster. I generally jump and growl and pretend to eat them. I can only do it for so long but they would do it for hours on end.''

Toni is enjoying every aspect of motherhood and recently took Sage to see the 'Cinderella', and the little one was delighted with the performance.

She told People magazine: ''I took my daughter to see the musical 'Cinderella' and she loved it. Just seeing her so overwhelmed with excitement made me get teary.''

Despite having two young children, Toni still swears as she finds expressing the right curse word feels very ''satisfying''.

She said: ''I find swearing quite satisfying when used appropriately and in context. And it's quite often, which is why I can't remember the last time I did it.''
