but why jump at every cry.how will they ever learn to self settle?
I know what it is. I've looked it up and have seen it discussed before.
The thing is, it's a bit of a paradox. As I said - if you go to a baby straight away, it learns that you are going to come straight away next time, so it doesn't cry as much next time.
If you don't come, it thinks 'ah, no one can hear me' so it cries harder, which isn't good as crying is fairly painful so it then gets a sore throat and cries even more because it hurts.
You can see why going to it straight away works better and results in a more confident baby who knows it will have its needs met.
Obviously if you NEED to leave it for a few moments because you're on the loo or whatever - that's normal and no way round it.
Gradually as a baby gets older you will find you can wait slightly longer, as by then it knows you'll come soon. And this is how children learn to separate, and to settle themselves, and so on - by being responded to when they were too tiny to do so themselves.
Ten weeks is too small to do this. A baby can't solve its own need for comfort, for sleep - and it is likely hungry or has tummy ache anyway (always wind after a feed, obviously, to minimise this)
at this age they cannot manipulate you any more than a kitten can manipulate its mother. They only have needs, not wants.
Once they are huge toddlers they can safely be ignored when having a tantrum or something, though genuine crying should never be ignored.
