Holly Madison will take her time to lose her baby weight

She said: "I'm going to get healthy, but I'm not going to focus on how fast I'm losing weight. I don't have a time limit. I feel different. I'm not used to feeling like this. But I don't feel the pressure. I'm just going to get healthy."

And Holly - who also has Rainbow Aurora, three, with her husband Pasquale Rotella - loves being a mother to two but admits it has been a big "learning process".

She added: "It's been nice. Not a lot of sleep, but it's been nice. I just put the month aside to try and get a new routine with the two kids.

"I thought I'd been through the baby thing before with Rainbow and I'd got it down, but juggling with the two kids is something new ... It's a learning process for sure."

Meanwhile, the 'Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny' author also gushed about her daughter's bond with her new brother.

She told People magazine: "Pasquale and I have been talking to her about getting a brother or sister long before I was even pregnant. We were trying to get the idea in her head, like, 'You're not the only one, so chill!' And we got some gifts from friends, like 'I'm a big sister'-type books. Those helped a lot.

"Their sibling bond is so valuable. It's so great to have that person who has the shared memories of growing up. It's her own little team. It'll be so cute to see them play. It will be really interesting to watch how that develops."
