At the moment Summer is her only child with her ex-husband Harry Needs.
The pair were married for a year-and-a-half and are said to remain on amicable terms. They announced their separation earlier this year in a statement that said:
"It's after much thought and sadness that we confirm our separation.
"It is on amicable terms and we still remain close friends.
"We move forward with respect for one another and our focus and commitment is on parenting our gorgeous daughter Summer.
"This will be our only comment on this private matter."
In the past Rebecca has spoken about the difficulties she's faced being a parent:
"Being a parent is bloody hard work.
"A lot of mums take six or eight months off. I had two months and then had to go back to work.
"I want to sit and be with my daughter and just have time together. But it isn't possible because I'm supporting the family."
Since their split the pair have been co-parenting and Rebecca reassured that they both work and balance it. Rebecca also revealed that Summer, "gets enough attention, trust me that girl is not spoilt of that, that's for certain."
And when asked whether she wants to expand her brood the Olympic swimmer said: " Not any time soon, but yeah I would love her to have siblings in the future."
"But you just never know, I'm very happy with giving her all my love and attention right now. We'll see in the future, who knows?"
