Congratulations once again ... I have Leo nephew, he's an adorable kid, outgoing, unafraid to speak his mind, challenging (please remember that one), very much a people person and all I can say is that, the worst thing you can do is trying to be nice in order to get his/her love. He/She will make a mess out of you. It's okay if you're a bit strict and hard at the beginning. You'll get his/her respect and once you get that ... He/She will love you for the rest of his/her life. I promise!
Also give him/her lots of hugs, affection, reassurance and you'll be fine.
