He has called his daughter “wonderful” in the past and admitted having her made him realise how much he wants more children.However, that doesn’t mean he didn’t worry about fatherhood initially.“I know it’s very natural to keep saying, ‘It’s a miracle, she’s a f**king miracle,’ but she is.“When Ayda was first pregnant we’d have a week of me saying, ‘I didn’t want this. 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 Dad launches daughter in to the air 40 year old dad trantrum - so good!
