Sometimes I think some of our sleep "issues" are twin related. While most of the time they're adorable and do entertain each other etc, we definitely have moments of attention issues.
Just this past week, our new biter Quinn chomped on Avery's cheek vying for a seat in my lap (parents out there, never get mad at daycare over biting. If it can happen in mom's lap, imagine how easy it is with a 3 or 4 to 1 ratio). Fighting over laps is the big issue right now, even when two laps are available, and there is plenty of fighting over toys and books.
I think we are also starting to see the ease of one v one parenting versus two v two. Unlike in rugby (in my opinion, more skilled athletes may disagree) 1v1 with toddlers is quite a bit easier than 2v2 since by themselves there is less screaming and no egging on (can you imagine what this will be like at 2.5 or 3? Hahah). I think we need to start taking them out solo a couple of times a month.
