If anyone knows how Serena Williams feels chasing grand slam spoils and toddlers at the same time, Kim Clijsters does.
The last of only three mothers to win a major, Clijsters claimed the first of her two US Open crowns 19 months after giving birth to daughter Jada in early 2008.
The Belgian was 26 at the time.
At 36, Williams is a decade older and bidding to achieve the feat in half the time.
It will be just 10 months since Williams had Alexis Olympia when the American walks on to Centre Court for Saturday's Wimbledon final against Angelique Kerber.
"If anybody is capable of doing that, I think she is," Clijsters told AAP at The All England Club.
"But I can only say what my challenges were because I'm not in Serena's body.
"It's balancing it all. When I talk to my girlfriends, whether they work in a hospital or as a doctor or as a dentist or whatever, the balancing part is hard for everybody.
"We (as tennis players) just have the physical part that comes added on to that. With us, our work is to physically be able to make our bodies ready to compete for two or three tournaments in a row, or seven straight matches in a row at a grand slam.
"And that becomes your focus, first of all, and that takes time. You can't force that, or can't push that any faster than you want because it takes time."
Williams has said as much herself, conceding she feels guilty separating herself from Olympia for long hours on match day and sad for missing her daughter's first steps.
"I had that feeling very much," Clijsters said.
"But when I talk to other women, they all have that. They have a hard time dropping their baby off whether it's at school or in day care or wherever. It's tough letting go."
For the most part, Clijsters found tennis a nice distraction - and even "like my psychologist" after the death of her father the same year she first reigned in New York.
At other times, she found her mind wandering to Jada during matches.
"Little things like if I knew she was in the stands and you were like wondering 'does she have sunscreen on when the sun comes out?' or is she drinking enough water?'
"Things like that you do worry about."
For the most part, Williams is enjoying the ride with Olympia in the stands.
"I was expecting a few more baby steps myself," she said while striving to become the first tennis super-mum to win Wimbledon since Evonne Goolagong Cawley in 1980.
"It's been a crazy 10 months. I was still pregnant at this time last year. That's something I have to keep reminding myself.
"Also going out there being a mum is super cool. Knowing that no matter what happens, I have amazing support and unconditional love. It's such a great feeling. I really can't describe it, to be honest."
Victory over Kerber would also draw Williams level with Goolagong Cawley's fellow Australian Margaret Court - the only other mother to win a grand slam singles title - with an all-time record 24 career majors.
"To be perfectly honest, I haven't thought about that this tournament. Not even once actually. In fact, I've probably forget about it," Williams said.
"That's a good thing because I put so much pressure on myself when I was trying to get to 18, then the rest, it was so much.
"But, as I said in the past couple years, I don't want to limit myself. That's what I was doing in the past; I was limiting myself.
"It's just a number. I want to get as many as I can."
