Baby Project, Newborn Baby

Today is the third day of carrying my baby around. Today the father took the baby for the first four periods and i carried the baby for the last four periods. The baby is getting even harder to carry and it gets in the way more and more everyday. When I carry the baby I can really feel how much it weighs and it sometimes even hurts my arm if I have to carry the baby for long periods of time. I don't what I would do if I was a single parent and had to carry my baby around all day...thank goodness for my partner.
