"🌸Welcome to the world - Arna Leia Pearce 💛" Kayla wrote on Instagram.
"I just stared into Tobis eyes the whole time during delivery, nervously whispering 'please let her be healthy, please be okay, please be okay' and Tobi kept repeating 'I love you so much - she's going to be healthy it's okay just breathe it's okay'.
"We both were crying. In that second, we heard her cry for the first time, the doctors and nurses examined her quickly, bought her over to us and said 'she is absolutely perfect'. My doctor said 'Look at that hair and those cheeks! Amazing!'
"I don't even know how to describe how I felt in that moment. I looked over at Tobi who looked like the proudest Dad I've ever seen, with tears running down his face he gave me a kiss on the forehead and whispered 'she's so perfect, I love you'.
"She is perfect indeed! From the start, she knew exactly who we were and was instantly calm. Tobi went into 'Dad mode' straight away. From someone who made jokes the whole 9 months about not being able to change a diaper ... to now not wanting to let ANYONE change her because he wants to help - has made me love him even MORE.
"Tobi wraps her up and cuddles her and she goes straight to sleep 💤 She's a happy quiet bubba who LOVES her big greek family😍 As for me, I ended up having a cesarean, as recommended by the doctor. I was a little bit sore, but after a couple of days I was generally fine, just no lifting other than Arna. Now, I just need to rest, eat good food, drink lots of water and I'll be okay! I feel so BLESSED right now.
"I AM blessed to have Tobi and my family be there every day. I am so thankful to have the most amazing doctor and midwives ever to help me.
"This experience has been amazing for me and I am proud to say that💛🌸. Thank you everyone for being SO amazing!! We are so in love and happy. Holding her for the first time in our arms was truly the best day of our life💕"
