My daughter is 10.5 months. Until she was 10 months we'd gently got into a good sleep routing. She's been in her own room since 6 months and would go down with a bottle at 7pm and get up at 7am. Of course she sometimes woke and (often) woke up early, but she was pretty content. Suddenly, out of nowhere she's started waking up with an anguished howl at between 1am and 3am and taking a bottle and up to 2 hours to re-settle. Is this normal? Is it a phase? Am I destined for months of horribly broken nights?
Help!
