All solutions sound kind of good. I'm surprised that no one has mentioned the tried and (sometimes) true method of holding the child and rocking him/her to sleep. Try looking up The Harsh Baby Lulliby by Rosalee Sorrells. It's a soothing little ditty that helps to keep parents sane during this time. Is there a LaLeche club near at hand for mom/mum/dad? Even if the baby isn't breastfed, they can offer advice.
