Great question - my belly is quite big as soon as I get in the shower in the mornings until when I get into bed at night, but first thing when I wake up in the morning it doesn't seem to be there! I was wondering where everything goes too? Although, if I compare my 4wks photo to myself now I guess I should know the answer - my waist is just so wide now - I used to have hip bones jutting out the front and now, well a 6 inch baby can fit it there for sure!
