I have one dd nearly 6 months. She's has slept an uninterrupted 9 or 10 hours overnight since she was 5 weeks old. She self settles and always has, is a happy smiley baby. I realise that sounds like a gloat but it's not, it's the truth. Sometimes I think she's like this because she was ill for the first week of her life and we weren't able to pick her up.
Anyway, I'm considering number 2. But I'm terrified. This is all I know. Did everyone that had a sleeper for their first have a non sleeper for their second?
