This is only my opinion but buying maternity clothes...(for me)...was extremely fun with #1 and #2...been there done that!! I say if you have to, go to Lane Bryant or hit up a plus size section of like a Fashion Bug to get bigger fitting clothes (if you have to go that high up). They are so much cuter and don't look like moo moos....not that the maternity clothes these days really do...it's just it's soooo expensive. I personally just got XL clothes and then went up to plus when I got really big. Since you have three in there, you might need some more room...plus might be the way to go. I got huge with all my pregnancies and even XL maternity pants fit wrong...but plus fit great. Other places to find affordable maternity clothes is Ross and Burlington Coat Factory....if you didn't know. Toward the end of this pregnancy I started wearing dh's sweatshirts...lol.
I find that Walmarts formula (Parents Choice) is very affordable and my kids always did great with it. I nurse mostly but do supplement when I can't be with baby.
I'm sure you know all of this though....lol.....
Other then being bummed about having to look for maternity clothes, how are you feeling?? Can you believe you are having 3?? I'm still stunned!! You gotta tell us when you start to feel them!
