My DD will only nurse lying down in our dark bedroom. She still nurses every 2-3 hours during the day which makes going out for any length of time difficult. I have had a little luck getting her to nurse in the sling while we are at the playground with our 3 year old, but just for a few sucks here and there. She used to be great at nursing in the car or a chair when we were out (not as great as at home, but at least enough to hold her over), but no more. Any tips on getting her to NIP again?
