Japan’s Osaka returned to the WTA Tour in January after the birth of her first child, daughter Shai, in July 2023.

Since then, the four-time Grand Slam champion has struggled to rediscover her best form and been unable to advance past the quarter-finals at any tournament.

“My biggest issue currently isn’t losses though, my biggest issue is that I don’t feel like I’m in my body,” Osaka, 26, wrote on Instagram on Tuesday.

“It’s a strange feeling, missing balls I shouldn’t miss, hitting balls softer than I remember I used to. I try to tell myself, ‘It’s fine you’re doing great. Just get through this one and keep pushing.’ Mentally it’s really draining through.”

Osaka was defeated by American Ashlyn Kreuger in the second round of qualifying for the Cincinnati Open on Monday.

“I’ve played a handful of matches this year that I felt like I was myself and I know this moment is probably just a small phase from all the new transitions (clay, grass, clay, hard), however the only feeling I could liken how I feel right now to is being post-partum,” she said.

“That scares me because I’ve been playing tennis since I was three, the racket should feel like an extension of my hand.”

Despite failing to reach the third round of a Grand Slam this year, Osaka has shown she can still compete with the best players – pushing current world number one Iga Swiatek all the way in a second-round thriller at the French Open in May.

However, she said she does not understand “why everything has to feel almost brand new again”.

“This should be as simple as breathing to me, but it’s not,” she added.

“I genuinely did not give myself grace for that fact until just now.”

Osaka is set to play at the US Open, where she is a two-time champion, later this month.

While many people share the joys of motherhood, certain aspects often go unspoken.

Here are four things that new mothers may find themselves grappling with:

1. The fear of dying: Before motherhood, we often take our own lives for granted.

However, when you become a mother, the fragility of life can weigh heavily on your mind.

Suddenly, you develop a fear of the unthinkable—leaving your children behind.

The responsibility of nurturing and protecting another life can make you hyper-aware of your vulnerability.

2. Concerns about parenting style: Every mother strives to be the best parent they can be, but self-doubt can creep in.

You may question your parenting style, wondering if you’re making the right choices for your child’s well-being.

It’s common to worry about whether you’re striking the right balance between nurturing and discipline, setting boundaries, or providing enough love and support.

3. The constant worry: Motherhood often brings a constant undercurrent of worry.

From concerns about your child’s health and safety to fretting over milestones and developmental progress, it can feel like your mind is always occupied with concerns.

This level of vigilance can be exhausting, but it’s also a testament to the deep love and commitment you have for your child.

4. Self-identity shift: Before motherhood, your identity may have been primarily centred around yourself.

With the arrival of a child, you undergo a significant transformation.

You become a different person, defined in many ways by your role as a mother.

This shift can be both beautiful and challenging, as you navigate the merging of your pre-motherhood identity with your new role.

Motherhood is a journey filled with ups and downs, you’re not alone in experiencing these emotions.

As you grow as a parent, you’ll find your unique path through the challenges and rewards of motherhood.
