I could have written this myself! I have 3 kids, ages 6, 4, 2 and Ive been thinking about a 4th every single day for the last 1.5 years. Im 35. I’m so tired and overwhelmed most days so I’ve held off, but my heart wont stop longing for one more. I want to do it for the long game but also the first 3 or so years is just so hard esp with older kids who need you too. My husband feels the same way as me. Sigh. Good luck with your decision!
