Hey Congratulations Soror!
I'm not expecting but I do have a two-year-old and although he's not that terrible he is a piece of work and I enjoy every minute of it (well most of the time)
My advice to you is to get as much sleep and free time as you possibly can right now, store up, take pictures and remember it fondly because in a short time most of your free time will be devoted to the little one!
On another note, just off the top of my head once you know what you're having (if you decide to find out) or even if you don't, if you purchase any clothes, diapers, shoes, etc. for baby buy them in different sizes and suggest that family members do the same. Most times baby is all set for the first thre to six months then after that they grow like water and you'll end up coming out of your pocket with a lump sum to build baby's wardrobe, (unless you know someone with a child who kept their baby's clothes).
At any rate feel free to email me at any time with questions.
Good Luck!!!!
