Feel like a rubbish Mum tonight!

Freya has been taking MTX since July. (10mg weekly dose - so 4 2.5mg tablets.) Freya is four and a half.
When she first started taking them, she was brilliant and took them with water and was really proud of herself, as were we and we made this clear. This lasted for a few weeks, since then she has had lots of treatment, appointments, etc and of course the blood tests.
The blood tests have become more traumatic. She used to just accept it and stick an arm out and not even cry. Now it is a real battle, even using Emla cream in advance. She had them done on Tuesday and was really distressed again, despite my having spoken to the nurse on the phone in advance, and in response, her giving Freya lots of time and emotional support.
More worrying is the tablet taking. She cried all the way home from school last Friday and begged to go to a friends house (she was avoiding going home cause she knew it was tablet day!). Lots of talking and giving her choice about when and how she wanted to take her tablets later and so today, she decided to take them before tea. We started at 17:20. She Cried and moaned and delayed in every way possible and evetually took the first one an hour and forty minutes later!! No, i'm not kidding! My husband and me sat with her the whole time, reasurring her and trying to be gentle and patient. She eventually took the second at twenty past eight! Yes, we had all sat there the entire time. By now she was so tired she was a mess. We had to give up and let her go to bed and she has promised to take the other two in the morning.
Apart from not being so tired I can't imagine it's gonna be much easier in the morning.We'll see.

Trust me, we have tried all the usual things - rewards charts, stickers, chocolate, choices, presents etc. She refuses to try to take it in yogurt or something else, and will only try with water/milk. She says she can feel them coming back up in her throat. Will be speaking to rheumy nurse again this week though I have already raised the issue and may requsest that we try liquid MTX. Anybody got any experience of it? I heard it tastes horrid.
We gave up tonight because although we didn't want to be in a position to say 'ok, don't bother taking them' and let her off cause this is the worst thing to do, but we both felt that what we were doing, for three hours was bordering on emotional abuse! We didn't want to traumatise her any more but really didn't know what to do for the best. We even rang the late night chemist for advice.
She went to bed happy bt I got the impresion she thinks she has won this round and I feel as though we were cruel making her sit through that, but then, as we explained to her, we are only doing it for the right reasons.
Any advice welcome. Don;t know what to do and feel completely rubbish as a mum having to put her through all this stuff. She's so little!
