Sometimes, when I am trying to get some work done while Liam is out - some writing/studying work - and Mikaela wakes up every 1/2 hour or so of her nap needing to be resettled, and the breakfast dishes are still on the table, the dishwasher still full, the nappies sitting in the machine waiting to be put out, and I am still in my dressing gown at 1:30 in the afternoon, with only half an hour to go before Liam gets home, and I can't find the particular book I need to look something up in because the last time I was reading it Mikaela woke up in the middle and I put it down somewhere other than where it belongs: sometimes, I think there is no way we should have any more children.
Other times, when I am simply engrossed in the delightfulness of Mikaela's enormous grin or Liams wonderful giggle - those times I think we simply must have one more.
Right now Mikaela has woken and is calling out - so right now I get to stop thinking about it and get back to living it. And the writing will have to wait (maybe I'll find that book in the mean time).
