Robbie Williams and Ayda Field to expand family?

Robbie Williams and Ayda Field want more children.

The couple – who already have children Teddy, three, and 21-month-old Charlton together – are reportedly keen to expand their family and are already working on it.

A source told The Sun on Sunday: "Robbie’s been telling people he and Ayda are trying for another child – and that they have been practising a lot.

"They’ve made no secret of the fact that they want to expand their brood.

"Now they’ve decided the time is absolutely right."

Ayda recently revealed that Teddy finally likes her younger brother after being "unhappy" about his arrival.

The American actress admitted that Teddy was "not impressed" with Charlton at first, but she has gotten over her sibling jealousy and now they are best friends.

She said: "When Charlie was born, Teddy was not impressed. I think she was indifferent bordering on unhappy about it. Now they just love to do everything together, I was tucking them in last night and I had one on each arm as they had their stories book and they were tickling each other’s faces and that’s just the best feeling as a mother."

Ayda has also praised Robbie’s fathering skills and said he loves taking time out from being a pop star to care for his kids.

She said: "Oh, he’s great. That’s what is so amazing is that he’s getting to see his kids. He’s so supportive, for a long time I’ve been by his side doing the wife and mom thing, and now he’s doing a bit of Mr Field stuff."
