One image of the slideshow showed Maria surrounded by all four of her children, including boys Patrick and Christopher.

‘You’ve taught me everything i know about motherhood, about unconditional love, kindness, acceptance and you mother with such joy and ease,’ Katherine wrote in the caption.

‘I hope to be half the mother you are. I love you deeply. ♥️,’ she later added.

Katherine was on The Drew Barrymore Show on Monday where she talked about her child she has with Chris Pratt.

‘She just turned nine months. She’s just the cutest little angel I’ve ever seen and I’m obsessed with her as I’m sure most parents say about their children. It’s the most fun role and experience that I’ve ever had and I love absolutely every single minute of it. It’s been such a joy, she’s perfect.’ she said. 

She also said she knew Chris was the one right away. 

‘We talk about that a lot because I’m pretty sure we both knew right away that this is where our relationship was headed and we clicked very quickly and so he is the best. And I am so, so grateful and it’s so beautiful to be able to watch him step into this new role of being a girl dad and he’s the best husband and best dad and I feel so grateful every single day for him,’ she cooed.

Now she wants to write a book about forgiveness. 

‘For me the interest in forgiveness really came when I realized that I was really struggling with forgiveness and my inability to practice it and I also didn’t know what it meant to me. And it really was just so helpful to me to hear other people’s experiences and to hear how some people have struggled with it and still struggle with it. How some people have been able to practice it. And also, we don’t really talk about it but we all will experience it at some point in our lives.’
