Kristen Bell doesn't think she's the perfect mother.

The 35-year-old actress, who has daughters Lincoln, two, and Delta, nine months, with husband Dax Shepard, says she still has a lot to learn about parenting and is just ''trudging along like everyone else.''

The 'House of Lies' star said: ''I don't really know how to do it perfectly. I'm trudging along like everyone else trying to do the best I can.''

The blonde beauty, who is glad her eldest daughter is ''wonderful and gentle'' towards her younger sister, thinks it's important for mothers to support each other.

She told ''I know when I was -- especially a first-time mom -- it can feel at moments ... as wonderful as it is, so isolating and all you want to know is that other people are going through it as well and you're not alone.''

Meanwhile, Kristen is looking forward to dressing her children up for Halloween next month.

She said: ''This year, we might all go as circus members because the baby really, really looks like a weightlifter and we want to give her little barbells. I like everybody being something as a part of a group. Last year, the two dogs and the baby were dragons and we were Khaleesi and Drogo from 'Game Of Thrones'.''
