My first two kids were wakeful kids who liked being with mum and dad. Still do. My 3rd has slept for longer periods at a much younger age. It's not because she is my 3rd, or i am more relaxed, or know what to do this time. Just a different child, with a different personality and different needs. I know i questioned whether it was me doing it wrong, especially when #2 was similar to #1, (and i sometimes still do on days when baby is not as settled), but when i am not sleep deprived i realise that i didn't cause sleep difficulties, and i did (and do) the best i can so we all survive and thrive.
