Thanks AllyDrew, useful to know. Think I will be giving it one more session and then leaving it at that. I can't afford to be wasting money on something that probably won't work.
El11, don't be daft lovely. Complain away! It helps to know that I'm not the only one with the incredible non sleeping baby. Besides, sleep deprivation is sleep deprivation. It all sucks.
When I think back it was 2 months ago that this every 2 hours malarkey started, while we were on holiday funnily enough. That coincides with his stomach getting upset and him not pooing for ages, and we're still having issues with him going now (struggles for ages, doesn't go for days etc) so maybe we need to address that too (have asked HV but they are next to fecking useless). He is probably teething too, I can see the outline on his gums of his top teeth and he keeps getting bright red cheeks.
I have a docs appointment for Friday, so I will ask while I'm there.
