DD is 10wks and daytime use of dummy is increasing, she probably now has it to settle for half to 2 thirds of her naps. She doesn't have it at night though (usually feeds to solid sleep) but isn't the thing with dummies and SIDS that the chance of cot death increases if a dummy is taken away from a baby that normally uses it? Should I get her to use it at night to reduce the risk? We co-sleep too...
