Hey, don't feel bad, I have three and I am still scared. It is normal to be scared, but use your resources. Take advantage of lactation counselors, walk in to a health department or clinic and just ask to use their scale (we did this with my daughter who was having problems). Most people are more than willing to help out. As far as changing a diaper, well, you may be slow at first, but now I am at #3 with 2 still in diapers and we have an assembly line. Lay down, take off one, clean, take off other, clean, put new ones on (my oldest helps with this part) redress. It would actually probably shock some people if they came in for our morning routine. You get the hang of it while you go. Be alright with being nervous because it is a lifelong fear. You will be afraid you aren't feeding them enough, then they get older and you are afraid they aren't developing right, then you get afraid they aren't learning enough and if what my mom says is true, then you start worrying about driving, alcohol, sex etc. etc. then the whole marriage thing, grandkids, and the list goes on. If you aren't scared at all, then you don't care. Fear shows that you care, you worry about your child. It is OK.
