Thats quite a difficult first soft toy project to take on, so kudos to you for sticking at it,
I have an old book "the big book of soft toys" that was mine as a kid & helped teach me to sew & I'm using it now to teach DD, theres a similar, if not the same pattern in it, but I would never of suggested DD tackle it first, as I know its a more difficult 1.....the one tip I would give, as you are getting confused & sewing things together that are not meant to go, would be to TACK it together by hand, with a very lose running stitch, before machining, that way you can be sure its right, & not a nightmare to unpick if its not......also with DD, we are writing in chalk on the back of each piece what they are, that seems to help her get them in the correct place.....helped me as a Kid too
