I need help, we sleep trained her at 6.5 moths very successfully as she never got past the 4 month sleep regression and woke 10 times a night. But as she hit 1 she has started standing in her cot at bedtime and crying, sometimes very badly, until we revisit her many times and eventually stay there stroking her belly until she sleeps. We are undoing all the sleep training and I'm not sure how to get past this as she gets really really upset if we don't go back and stay with her. Do i wait a bit too see if it passes and then sleeping train again?
