You're on to something Detective, I was two days early! 
Thanks for the offer Horsey, I managed to get some at the chemists so I'll give it a try and see how we go for now. Yeah Detective I was pretty unimpressed that the chemist sold it to me actually but if challenged I would have been able to tell her that the HV advised me to try it and that I was seeing the GP for a follow up on Friday so I'm sure I would have got it anyway.
Chasing I was wondering about that, maybe they feel safe with strangers because they won't be passed over to them for a cuddle, whereas if parents or in laws are around then the baby gets anxious because they know it's 'pass the baby' time and they'd rather be with one of their primary carers.
I bought one of those mesh things for feeding as I have some squashy kiwi fruits for J to try. Has anyone used one of them yet? What else can you put in it? I was thinking it would be good for strawberries.
Fluoxetine is prescribed for premenstrual dysphoric disorder which is super-PMT Chasing. That's in the States though, I don't know what you would get in the UK or Luxembourg though.
