The NFL star - who has Benjamin, six, and Vivian, three, with the model - hasn't ruled out the possibility of adding to their brood.

He said: "It's usually up to your wife, isn't it? It's kind of up to [her]. I never rule anything out."

The 39-year-old sportsman has enjoyed being able to make memories with his kids and is glad to have had the chance to do normal things with them like pick them up from school.

He added to E! News: "I've had time to bring them to school and pick them up from school, put them to bed and read books.

"Everyone says, 'It goes so fast! It goes so fast!' And it does go so fast, and you enjoy these different moments that they have, because, you know - it's only once that they get a chance to have their first day of school. To pick them up on their first day of school is so fun. Those are memories I'll have for the rest of my life, and hopefully they'll have them, too."

Meanwhile, the 36-year-old model previously revealed she tries to schedule some time to escape the stresses of motherhood.

She said: "I had to make some adjustments from what my life was like before I was a mom. My kids are so fun and loving, but they are also demanding!

"For me, making schedules are critical to make sure we attend to all the needs of the kids and our family. After adding everyone's schedule on the calendar, I make sure that everyday I have some sacred time for myself, so I can recharge."

Gisele also credits meditation for helping keep her focused.

She added: "I noticed every time I felt overwhelmed I would hold my breath. I had to learn to stop, relax and take long deep breaths and within seconds I would feel more clear and ready to deal with the situation in a more loving way. Meditation also has been a wonderful tool. I notice that when I don't take the time to do it, I am not as centred, patient or clear."
