Bless! 18 months is fairly young isn't it? I don't really know...my niece is 2 and she still wears nappies but I don't know if they've started to try and potty train yet. Hopefully your son will get the hang of it in the nick of time Sunshine
Don't worry about money - well try not to anyway! It will work out somehow, we've had plenty of scary times but always seem to pull through.
Mmleo it's kind of free here, but not. Our taxes go towards the national health service (NHS) so everyone has access to a doctor when they need it (though waiting lists are usually long!). Operations, blood tests, scans etc etc are free. The only thing you have to pay extra for sometimes are prescriptions but depends. Re fertility treatment I might have to pay the prescription charge for clomid, not sure. IVF on the NHS comes with pretty strict rules since the money for it comes out of the public purse like you have to be in a certain age range, no kids already etc. Some areas you're only allowed 1 shot, other areas you can have 3 attempts. Depends on your local authority and how they want to budget. Privately it is thousands so I hope we don't end up going that far as we def won't be able to afford it!!
