Disclaimer: I have two DC who have not always been brilliant sleepers and go through patches of wakefullness at night/early in the morning (!) but...
I have been reading some of the sleep threads and am really surprised by the number of people who have older babies or toddlers who sleep SO badly whilst claiming that they don't know how to improve the situation and won't do any form of CC.
From my experiences, babies have to learn how to sleep well and they do this by you setting up routines and helping them along the way. If you feed your 12 month old milk in the middle of the night, they will keep waking for milk in the night. If you bring them into your bed, they will want to be in your bed. If you have to lie down and hold their hand, they will expect you to be there holding their hand if they wake up.
Nothing changes overnight and teaching your baby/child to sleep well takes patience and consistency. But leaving a baby to cry for 5 minutes is not going to hurt it and ignoring a toddler whilst you drag them back to bed and not give into their ridiculous demands is not difficult. We are the adults!
AIBU to think that some parents need to be a bit tougher rather than find some miracle cure for poor sleep habits?
