I've got one!
When i was at work the other day i was looking after a baby that was going into foster care. The foster mum and her daughter came to pick the baby up. They have had several foster children before and had another foster baby at home who was around the 10 month mark i think, so the little girl who was about 6 or 7 or 8 (i'm bad with ages) was used to having foster babies/kids. Never the less, she asked lots of question about why the mummy didn't look after the baby and why this and why that but the funniest thing was when she looked at her mum with all sincerity and said "mummy, who fostered me when i was a baby". OMG PMSL. It was sooooo cute, god love her!
