Announcement HELP!!!

Sydney-Marie • I`m 21 years old. I`m married. We have one daughter who we had at 19 year old. We live in a quiet little suburb. I`m a SAHM, and love it to pieces.
Plan to tell my husband next weekend and make it a surpise. We've been trying to months, and last time we had a MC. So I'm trying to make this one special but wait just a little longer into the pregnancy. Anyone have ideas for a cute note to put inside the box when I give it to him? I was thinking "Hi daddy, save these for me. We will go running on Oct 2016" but that doesn't make much sense. Although it matches his/her daddy but not for a newborn baby. Ideas?! 💕
