When you have kids, time is measured by their milestones. Sleeping through the night. Eating solids. Smiling. Time is all relative; no child reaches those milestones at the same time as their siblings. Meg got her first tooth when she was 4 months old. Drew's was closer to 8 months and quite frankly, I can't remember when the girls got their teeth, but I know Annie was first. Annie was walking at 10 1/2 months; Izzie was almost 15 months old.
Having twins makes milestones a little bit different. The girls are not identical. Annie is 3 inches taller than Izzie and 5 pounds heavier. Izzie speaks better than Annie. Annie's hair is darker than Izzie's. Annie is using a booster seat in the car, but Izzie is still too little to do so.
However, having twins also means that some milestones have to be attempted simultaneously. We took them both out of their cribs and put them in toddler beds at the same time. We started potty training them at the same time. They stopped drinking out of sippy cups and drink out of "big kid cups" at the same time. We are quite fortunate that they WANT to do these things together. They cheer for the other when they a)poop on the potty, b) zip their own coat c) put on their own socks.
It all seems like it's happening so fast. Two months ago, they were both still in diapers all day long. Now, they're both wearing undies and Izzie is waking up DRY in the morning (in a pull-up no less); Annie is getting closer to that milestone every day. Two months ago I was still zipping both their coats and now they either help each other or do it themselves. Two months ago we were still giving them sippy cups because they were still throwing them on the floor for fun. Now the each drink carefully from a cup.
I don't think this would bother me as much if all these milestones weren't the last milestones that I'll be seeing at this age. I won't have to potty train anymore. I won't have to get another child out of a crib. Part of me rejoices at this, of course, but part of me is sad that it's over. My babies aren't babies. I have four kids. Now my blog name finally means something.
