Katie Holmes has admitted she struggles as a single parent.

The 'Days and Nights' star - who has 8-year-old Suri with ex-husband Tom Cruise - has revealed she doubts her parenting skills on occasions.

She told PEOPLE magazine: ''You do the best you can. Some days you feel really good about yourself and some days you don't.''

Katie - who divorced from the 'Mission Impossible' star in 2012 - believes support from other parents makes things a lot easier for her.

She explained: ''You really need to support each other, help people through whatever it is they're going through -- whether it's: 'My kid just threw a tantrum' or 'I was late for graduation' or whatever it is, you know!''

Meanwhile, the 35-year-old - who has help with Suri from a ''ready and willing'' mother and nanny - has admitted she'd rather spend as much time as possible with her daughter.

She said: ''I do have help yes, but it's your baby, you know? You want to be the one who was there.''

Despite finding being a single parent challenging, Katie believes it is important for parents in similar situations to her to do their best and not feel pressured by the expectations.

She said: ''I think we all need to just ease up.

''Ease up on the expectations, and the worrying. We're all trying to do the best we can.''
