I also miss those days, sticky wee hands thrust into yours, hysterical laughing 'cos someone said poo, sweaty wee faces sleeping in buggies etc.
There are new joys though, chatting about stuff that is a bit more interesting than pokemon evolutions, going for a pint, watching a movie that you all can enjoy that is generally not animated, watching them learn to be adults and providing a different support from kissing it better and giving them an ice-pole.
If i'm honest, I think i like the teen years the best but I'd trade a weeks holiday to go back and snuggle with my little babies for an hour.
