starting to get a tad freaked out

i made my first official baby purchase last night.  like a high dollar item that made me cringe when i signed the receipt.  we've saved everything from both boys, last time there were a few things we needed to replace, but beyond getting kman new furniture, we didn't need to invest in much.  this time, we need to replace some of the bigger items, like the stroller, infant carseat, baby monitor, etc...  the infant carseat expired like a year or so ago and i think its time to say good-bye.  we could probably get by with using it, but why take the chance?  the stroller is a mess, squeeky crazy wheels that require a lube job before venturing out.  we've had nothing but love for both of these items and we have def gotten our money's worth for sure.  i think buying new items, i know we are only using for this baby, makes it harder to spend the money?  i am a cheapskate anyway, so the fact that i can't buy this at bargain basement prices stinks.  BUT i did use a coupon and the only reason i purchased it last night is the manufacturer is offering a rebate if you purchase by the 21st...so there you are.  in the end i'll save over $95 which doesn't seem too bad, when i could have totally walked in and not saved one single penny.
both of the boys made the trip with me, we had actually visited the store over the weekend and i took them, just to verify this stroller/carseat combo was the one i wanted for sure.  they didn't act up too much, but i LOVED the look i got from the newbie pregos and their spouses intently looking over their registries. 

this morning my little doodle, kept repeating how we bought the stroller for the baby.  i liked that he remembered and that he's putting some thought into the fact that eventually there is going to be another little person running around.

ok, so now i am freaking out.  THERE IS GOING TO BE ANOTHER PERSON RUNNING AROUND OUR HOUSE?  what the heck was i thinking?  AHHHHHH!   i guess the fact i am almost at the half way point and starting to buy things has really started to sink in.  seriously, there is a baby, an actual human BABY in my belly growing and going to be here in like 22ish weeks.  um, is there anyway to extend that?  (ok, in 22ish weeks, i might be thinking otherwise, ok, i know i will be) and i am pretty sure i'd like to get my body back at some point, but seriously in 22ish weeks there is going to be a baby. 

i am sure i went through this before and i think some of this has to do with the fact we haven't had a chance to get anything ready, and i guess i am nesting or should be and i am not, so instead i am freaking out.  surely, this is normal, right?  surely?
