Melissa Joan Hart's children are making her ''broke''.

The 38-year-old actress - who has three children: 8-year-old Mason Walter; Brady Hart, 6 and 2-year-old Tucker McFadden with husband Mark Wilkerson - says her wallet is shrinking because her kids are losing so many teeth.

She joked: ''[My sons are] losing a lot of teeth right now. The Tooth Fairy has come a whole bunch.

''I'm going broke - she's going broke!''

The 'Sabrina, the Teenage Witch' star also admitted that her youngest is keeping her the busiest.

She explained: ''Tucker is starting to get very spunky. He's got a lot of sass to him right now. A lot of talking back. A lot of his own opinions.

''That's fun and interesting, but it's hard not to laugh and make it a habit.''

Meanwhile, Melissa has revealed that she is excited for to spend time with her family at Christmas.

She told ''We always have lots of family around so this will be the first time it will really just be about [husband, Mark Wilkerson] and our kids.

''It'll be [an] exciting, calm, quiet, peaceful Christmas ... which is weird because that doesn't really seem like Christmas to me. Christmas is chaos and family and lots of food and lots of people.''
