Hilary Duff admits she was shocked at the lack of sleep
The singer-and-actress welcomed son Luca Cruz into the world five weeks ago and while she loves being a mother, she confesses it`s not always easy.
Hilary - who is married to former ice hockey player Mike Comrie - said: "The first week I was like, `I`m doing this, I`m good. I can not sleep, I can do this.` I don`t know where you get that energy from. Then it hits you - the fatigue.
"So many people were like, `Take naps when your baby naps.` So I tried and it really helped a lot. I thought when he was napping that was the time I could do all the things I needed to do. It`s a fine balance."
Fortunately, little Luca is proving to be a good baby although she isn`t convinced it`s going to last.
She told People magazine: "He`s really a good baby, I promise. He sleeps really well and he`s on a good schedule. He sleeps a good five and six hours a night, which is just amazing. I am so grateful.
"I`m waiting for the tables to turn. I`m like, `How do I have this wonderful baby?` My mom said when I came, she was like, `Where can I send you back?` It was nothing like with my older sister Haylie."
