Jenna was a shocker for not sleeping if she wasn't wrapped. We had to swaddle er so tightly until she was about 6-7m. Really strong startle reflex!!

Hamish is heaps more cruisy - he likes his hands up by his mouth, it will make him settle instantly.

I am doing the yo-yo baby thing all day. It takes me about 3 goes to get him to sleep, but usually in the afternoon he will go down for 2hrs or so without stirring. Bliss

I'd suggest trying new swaddling techniques and maybe a different sort of wrap. Get those arms wrapped down!!!
