I have dreaded this day, purely for selfish reasons. Those 3 hours a day that dwindled gradually down to an hour a day, was still my time, my sanctuary in the middle of the day to recoup, sleep, relax, read or get jobs done.
Not having a nap in the middle of the day means going out for the day or getting things done in general is easier as there's no rush to get back for nap time. So life in that respect gets easier. However if you fall asleep in the car on the way home from somewhere, even for just 15 mins, it means bedtime is a struggle as you won't go to bed at your normal time.
Now the big question is, what do I do with you for a WHOLE day? How do I keep you occupied, entertained? It used to be easy. We'd go out in the morning to an activity or play date or to run errands. Then lunch, nap and then there was only a couple of hours until dinner which we filled by playing and watching tv. An extra hour or so each day doesn't sound like much time to fill but it really makes the whole day stretch out in front of us seemingly never ending. And as your attention span for each activity is still only roughly 10 minutes, that's a lot of activities I have to find to entertain you!
I'm sure after time it will become normal though, and we will just naturally fill our days. It's still a daunting prospect though.
Another sign you are growing so fast.
