My family. I couldn't get through anything without them, especially my husband and kids.
Also, my big brothers sarcasm, he never fails to make me laugh and reading back through some of the texts we've sent each other over the months gave me a much needed giggle last night. For example when I text him to say I'd gone into labour (last month), he replied "wow, and I'm on the toilet so know exactly what you're going through" lol I don't think he knows quite how much I adore him!
