My DS is 2.5 years. He had been a brilliant sleeper from 10 weeks sleeping from 7pm to 7am. We recently gave up his dummy (used only at bedtime) cold turkey & he seemed fine - cried for 2 nights at bedtime but then seemed fine. However after 1.5 weeks he had a cold & started waking at night unsettled a few times wanting a drink, cuddle etc & then after 2.5 weeks he is still doing that but also waking at 5 - 5.30 am as well. We are both so tired now I am tempted to go back to the dummy as he is v tired & so are the rest of the family.. it's a grouchy household - should I go back & try again in 6 months or persist & get through it?? (he still has a nap which I have scaled back bit he is so tired now as waking so early - it is chicken & egg to know the problem)
