sigh. i'm going to do that this coming week. i got some $$ from relatives and am going to use it to buy a few cute new things to help me get through the summer since none of my regular summer clothes are going to fit me.
as for the belly tightening back up, i think it's really different for everyone. but mine has so far bounced back pretty quickly after both #1 and #2, and now that my uterus has shrunken back down to normal size it's mostly already flat again.... mostly. i attribute what's left to needing to retone those abdominal muscles - i've got a pretty good separation of the rectus abdominus right now - and also the extra 20 pounds i'm carrying.
i like OA's suggestion of shorts and a t-shirt. i might try that if i'm going to be swimming in public. but we have a pool at our house and no nearby neighbors, so i'd rather not have unsightly tan marks down to my knees and elbows

so i don't really care too much what it looks like as long as it fits and i can get my boobs out relatively easily to nurse. my skinny bathing suit is a halter-style tankini, and that worked great for nursing (and for covering tummies) so i'm going to see if i can find another like that.
