As an aside to the Whisperer thread on the sleep forum, I was wondering - does anyone else find it nigh on impossible to differentiate between their baby's cries? My daughter is only 6 weeks, and try as I might I can't work out any difference. I know in her book Tracey Hogg says that if you don't respond appropriately to the differing cries, then they stop being different and just become crying. Is this likely to have happened so early, or am I just not very perceptive?
