First time they call you Mum. First time they trust you to be the parent. First time you have them dressed head to toe in clothes you have bought. First haircut with you, first dentist, first time they let you hold a sick bucket and mop their brow.
First day at new school, first day running across the playground to you, first friend round to play.
First birthday with you, first Christmas with you, first holiday, first passport in new name, first photo with grandparents, first time they play with new cousins.
First big tooth, first pair of grown up shoes, first time learning to ride a bike, first time bouncing on a trampoline in your back garden.
First time creating your own traditions, first time they ask for stories about your own childhood, first time they gang up with grandparents against you, first time you laugh yourselves silly over something you do together.
It won't all be roses, obviously. But every first time with you is a first.
