On her elbows, try a little vaseline or a good lotion or cream like Eucerine or Nivea (look for something hypoallergenic). Also, with a baby that small, you only want to bath them every couple of nights especially in cold weather. Make sure you don't take her outside for an hour or so after bathing, too. Bathing opens the pores and can leave you vulnerable to chapping especially in the cold. Sometimes, though, in spite of everything we do to prevent chapping it still happens. I usually try vaseline at night and some lotion or cream during the day when it happens. My sister (a nurse) recommended the nivea or eucerine creams to us. The creams usually work a little better than the lotions.
Also, if you are looking for a supportive environment to meet new friends, I'm part of the MOMS Club of Pittsburgh East. It is a wonderful place to meet a diverse group of women. I have yet to find a member of the group who is not friendly and supportive. If you want more information, please email me.
