Hi,

Your baby does need to be gaining weight overall. However, one apparent weightloss isn't cause for panic - it's just an indicator that you should look into the situation. I have seen many panics initiated because of a variation in scales, but on the other hand it would not be prudent to "do nothing". In the short term the simplest thing would be to wake your baby and feed him in the night. Most babies will still wake to feed at night at this age, but some get a bit too settled a bit soon. You can wake him anytime it suits - some mothers might give a late "dream feed" before midnight - others prefer a good block of sleep and might wake the baby later. Get your baby weighed on the same scales in a weeks time. Babies should be feeding 8 times or more in 24 hours at this stage.
