puea, mrs Tan, SSL: No no no, pls dun think that real contractions are those that come v sharply then go away! The way to know if it's REAL contractions is by TIMING. They should be regular in the sense that they come at every 15min or however many mins interval, and the interval becomes shorter as time passes and the pain itself could also stretch a longer time as contraction progresses. This pain should not go away or lessen in anyway however you may change your position, whether you are walking, standing, sitting or lying down.
Mayday: yup, MUST use nappy cream at EVERY diaper change whether or not bb has nappy rash. Just one dirty nappy without the barrier cream can give bb a nasty rash.
