THIS is the most heartbreaking part of being a parent (according to Katie Holmes)

Raising children is full of moments that ar equally filled with heart-bursting joy and also this lingering feeling that time is passing by so way too quickly. Like, much as I love having this funny, gorgeous, kind, witty and compassionate seven-year-old – my mini best friend, I also look at her every day and think "how are you seven already?!" I look back at pictures and Facebook memories and Instagram posts and remember like it was yesterday the day she was born and the day she started walking and the day she became a big sister and the day she started in kindergarten in Oslo – all those months and days and even years ago now. This feeling, this heart-wrenching knowledge that our children are growing up a little more every single day, is universal, I think. We all feel torn about the joy it is to see them grow and develop into these amazing people, yet can't help but feel sad that they are doing just that. Actress and mum-of-one Katie Holmes recently opened up to Town & Country magazine about parenting 10-year-old Suri, and how she now wants to make a career shift away from acting for Suri’s sake. "This business is so unstable, and you never really know where you're going to be," Holmes said about her desire to now move behind the camera. "The thing about directing is I can say I have this window and that's when we're getting it done. My child is the most important person to me, and her upbringing is paramount to my work right now. It's very important that I'm present and she has a stable, innocent childhood. I feel so blessed to do what I do, but there's nothing in the world better than watching your child succeed.” The 38-year-old also admitted that she finds it difficult to see her little girl, who she shares with ex-husband Tom Cruise, grow up and inch closer to her teenage years. "Every day, kids get a little further away from you," she said. "That's a positive thing. They should be becoming more independent, but it's heartbreaking. You want them to stay with you forever, but they're these amazing beings, and you have to do everything you can to give them what they need — and then they're going to go. And that's going to be very, very sad for me.”
