Meg, I know it's hard. My DS fought sleep 24 hours a day from 2 months til 13 months. He still doesn't love it, but it's better

I have to agree with the others, she will be picking up on your stress. The harder you try, the less likely she is to go to sleep. And I hate to say it, but it seems that the babies who sleep through as young as Isabell, often don't sleep well during the day. Put her in the pram, stick the earphones in and go for a walk. Keep trying the slings (I would have thought the HAB would be more comfy for her that the BB), sometimes bubbas just need to get used to these things before settling down. Try it when YOU are relaxed. If you're putting her in it out of total desperation she will likely pick up on that and freak out. Go for a walk with her in the carrier.

Sometimes we just can't change them. They might be little, but they are people, with personalities, and trying to make things different usually ends up stressing us out, because it simply doesn't work. I wish I'd given up fighting it earlier with my DS, and spent less time stressing and worrying about his sleep (or lack of). I know it's very hard when you're sleep deprived, but sometimes there's nothing you can do. As RF said, she's not doing it to spite you..........she's just a little baby, crying is her only way of communicating.

I read somewhere once that if the method you're using to put them to sleep doesn't work within 20 minutes, it probably won't work at all. It seems pretty true to me. Persisting past that amount of time would usually lead to tears for both of us. But if I stopped, played with him, whatever, and then came back and tried again, sometimes we would have success. It's worth a go anyway. Hang in there, it will get better, that is for sure.
