They make time for each other. [They] have sweet nights at home with Luca, cooking dinner and watching movies. They're closer than ever!"However, Hilary, 25, finds it "hard" to be away from her adorable son and has had to make changes to her lifestyle in order to ease herself back into work.She recently said: "It's hard to be away [from Luca]. I did a guest spot on 'Raising Hope' [and] I was so happy to be on a set again ... but it was hard. I also had a day of [thinking], 'I need to get home. What am I doing away from my baby?'"It's such an adjustment. It's a huge change and it took a few months for me to be like, 'OK, this is me now, this is who I am now, this is how I do things now.' "The actress is often spotted out with baby Luca, taking him with her to numerous social meetings, and as his first birthday approaches Hilary is already considering having another child.She said: "Mike and I are literally so obsessed with Luca. He's perfect! We should just be one and done. But I think once your kid starts getting older you miss that baby phase and you go in for round two."View the gallery for other photos of Hilary Duff doing tough pilates and working hard to lose her baby weight.
