"The ants go marching one by one, hurrah, hurrah. The ants go marching one by one, hurrah, hurrah. The ants go marching one by one, the little one stops to tie his shoe …"

"Wait, what Logan? I don't think it's tie his shoe on one by one.""Yes, it is.""OK, fine whatever."My husband, Bob, and I have learned to not argue with a 3-year-old because most of the time, you're going to lose - even if you're right. It's easier to pick your battles.But it has been amazing to see how independent this little guy has gotten over the past year.From wanting help doing everything to now telling me, "No, Mommy, I am doing that. Go sit down."Not that I'm complaining because it's nice to see this baby, who at one time was just a smooshy ball of pudge who couldn't even hold his head up, growing into this curious boy who has an extensive vocabulary that leaves my husband and I scratching our heads, saying, "Where in the world did he pick up that word?"Toddlers are fascinating creatures.Yes, they can sometimes be little homegrown terrorists who have better interrogation skills than our military and know how to push you to just before your breaking point, only to transform into the cutest little people you ever wanted to meet in under 2 seconds flat; but they are adorable and scary all at the same time.It's hard to stand by and watch as Logan grows though, absorbing everything in the world around him like a sponge and filing it away in his growing mind.This past weekend, Logan, Bob and I went to visit a preschool to start the process to sign our little boy up for 4-year-old preschool.He loved everything about it, which makes me happy and puts my mind at ease that he will be fine in the classroom.But watching him play with everything as we talked to other parents and the preschool teacher also made me a little sad though.It reminded Bob and me just how quickly time flies and children grow into adults, and before we know it, those preschool open houses will change into college searches.Neither of us is ready for that yet.But as a parent, will you ever truly be ready for any milestone in your child's life?No matter how old they get, you will always see that little boy who loved to cling to you, yelling, "Hey, Mommy," or "Hey, Daddy," even if they now tower over you.You will always hold your breath every time they walk out that door, only to feel relief when they come home safely that night.Nothing can prepare you for the feelings you must go through on this journey as a parent, but I'm learning that is OK.
