You f**king wanted this.’ But that was me just being scared,” he told British newspaper The Sun previously. “There have been times when I’ve wanted to run off. I will admit that. I start to think, ‘I’m not old enough for this and I’m still a kid myself,’ but I work it out.“I don’t think Ayda understands my worries sometimes. I told her I needed to change a few nappies to get my anxiety levels down.”Cover Showbiz You May Also Like Dad takes kid skateboarding and crashes Robbie Williams helps his wife in labour by dancing Dad launches daughter in to the air Become a fan of The Edge on Facebook and on Twitter .
