Honestly, I can feel my bottom lip wobbling now. He's 2.10 and the nursery have said that he's been allowed to visit the upstairs (pre-school, basically) room now and again and he loves it, so they're arranging a date for him to move up there and giving him time up there to 'integrate' him.
ANd of course it's lovely that my little boy is growing up but... but... he's really not my little baby any more now, is he? Waa...
