Background - DD is one and not a great sleeper but since the new year has improved and occasionally just woke once for milk, usually it was twice. That was fine. I have always gone to her when she cried or woke and comforted her.
The night before last she woke every 90 minutes and I'm not sure why, I gave her calpol, milk, changed her etc. I couldn't see the reason.
Last night she went to bed at 7pm, woke at 10pm and I gave her a bottle. All fine- usually she goes straight back to sleep. This time she woke as soon as I put her in her cot. I took her temperature and it was fine, gave her calpol in case of teething pain. Cuddles her and walked her around. If I was holding her she was fine she just didn't want to go to sleep. After an hour of me putting her in her cot and her waking up DH encouraged me to just leave her to it and effectively let her cry herself to sleep. DH has wanted to do this for a while as some of his friends have done it and claim their children now sleep much better.
She wasn't so much crying as shouting and protesting but I've woken up riddled with guilt and feel like I've ruined our relationship. I think it took her about 30-40 minutes to fall asleep. She is of course behaving normally today and seems happy and fine.
I guess I'm looking for informed people to come along and tell me either way anything they know about this.
