I hate the terms 'significant other' or 'primary care giver' because they sound too clinical for what a mother is.
But, everytime I walked into the room this weekend Isobel's face has lit up, she has smiled a smile so big I thought her face would split in two. It didn't matter who she was with or what she was doing, she smiled at me, a great big unsolicited smile.
I guess that makes me all of the above, AND her Mummy.
I don't know if she knew how much I needed that.
