Eric and Roselyn welcomed both of their children, Sebella Rose Winter, and Dylan Gabriel Winter, 5, via IVF. Although her first pregnancy was pretty much smooth sailing, the same can’t be said for the next time around.

​​“I was always the one administering all of the hormones because she doesn’t like dealing with needles. I had to give them to her every night,” Eric told PEOPLE via Yahoo News!, adding that Roselyn’s second pregnancy was “quite a journey.”

The couple shared that news of their bundle of joy came as a surprise to their daughter, who was eager to have a little sister. With this said, you could only imagine Sebella’s disappointment when she learned her mom was having a boy.

“She’s been asking for a sibling for quite some time and always just visualized it was going to be a little girl,” Eric told the outlet. “So when [she learned] it was a boy, she was a little pissed off at us at first.”

Though, she seems to have warmed up to her little brother since then.

You can see Eric on new episodes of The Rookie Mondays at 8 p.m. EST on ABC.
