haha trust me ure not alone… even i confused body suit for onesie. check the images on google.. body suit is as the same says full body suit.. ur baby will b protected and covered from top to his heels.. its really awsum for newborns…onesie is exactly same except its only till the kids’s pvt area(where u put pamper). ive been told my cousin who has 2 kids that body suits are best for any weather. although i will b deliverin in may and its damnnnnn hot in uae startin from april itself… they say body suits and receving blankets are still necessary to keep the baby temperature warm.. i guess their bodies are naturally cold or somethin…
i went crazy with shoppin like i said. but i dunno if my advice for goin crazy will b gud for u. i dunno how long u r gonna b there and plus its personal preference. i wanted to buy alot of clothes cus i m told babies dirty their clothes so i din want to take risk so i bought as and when i liked anything.
even i plan to breastfeed but i still bought 3 bottles.. of the smalllest size (in oz) its for newly borns who dun drink alot of milk initially… there were different sizes and my friend told me to buy the smallest.. cus as they grow their milk intake will increase. i bought plastic ones… i hvent seen any mother carryin glass bottles… happy shopppppppinnnnggggg 
which week r u in now?
