Victoria Beckham has bought baby daughter Harper kneepads for when she starts to crawl.

The fashion designer has invested in some Crawlings pads to protect her seven-month-old girl's knees when she begins to move around the floor.

Victoria - who also has three sons, Brooklyn, 12, Romeo, nine, and six-year-old Cruz, with soccer star husband David - posted a picture of the pads on twitter and wrote: "Amazing! baby knee pads for when babies start crawling!! X vb (sic)"

While little Harper is yet to start crawling, she is certainly keeping her mother busy as she doesn't sleep well at night.

Victoria was recently pictured looking tired and said it was because of Harper's erratic sleep patterns.

She said: "I'm not going to lie about it, I'm tired. I'm really tired but I'm also very happy with my life.

"I'm basically just like any woman who's working and has lots of children - it's tough.

"I'm not getting much sleep at all. Harper's not sleeping that great, and I've been taking Skype business calls throughout the night too because of the collections. I'm up with the baby as all mums are and I wouldn't have it any other way. There's not a team of people doing it for me."
