Cat - I am so sorry about your little girl:(
Pass, im no expert, but that ball sounds like myconium to me, perhaps that was what was blocking him up? Now he's passed it, he might be ok. DS pooed all over me after he came out, when we were doing our skin to skin and that's exactly what it was like.Mention it to the HV anyway, just in case.
Horsey - good that you're keeping food down, hopefully it's a 24hour thing.
Peaky - there's a product review section on MN, and a topic, can't link cos I'm on my phone, but look at the talk section and you'll find it:)
