I feel so sorry for my dd, she's just 5 weeks old and I've just changed her onto Sma white as she is a very hungry little mite. It does seem to have given her a bit of constipation though. She doesn't seem to be in pain but every now and then she's obviously uncomfy. I've been feeding her as much cooled boiled water as a 5 week old will take (about 2 oz if I'm lucky!) but just wondered if anybody had any other ideas?
