Serena Williams' baby videos are the cutest things on Instagram today

For Serena Williams, 2017 was quite the year - and now she’s capped it off in the cutest possible way.

In the space of 12 months, the tennis great won the Australian Open, welcomed baby Alexis Olympia Ohanian Jr, and then got married two months later.

“They say save the best for last,” the 36-year-old captioned her tribute to Alexis Olympia.

In another, the new mum says Alexis Olympia takes after her “Aunty V” - i.e. Williams’ sister Venus - because she has “very thin legs”.

Ohanian, co-founder of website Reddit, is front and centre in one video, showing off his daughter’s very chic donut-print outfit - and jokingly scolding his wife for how it was styled.

“What happened to her pants? Pull them up, I will not have sagging in this household,” he quips.

The high-profile parents aren’t shy about sharing moments of their daughter’s life on social media; little Alexis Olympia has her own Instagram account with almost 190,000 followers.

Undoubtedly, plenty more adorable videos of the bub will make their way into our feeds in 2018 - and there are no complaints here.
