hiya just want to have a wee rant here,sorry.dd4 had more bloods done few weeks ago and was brilliant.now we have to get a urine sample for acids ect,have been trying to get her to potty sit ,but its no use.shes still in nappies and has a meltdown when we put her on one.have contacted her peadi about it and he says try for another week, then theyll bring her into ambalutory care and do a catheator or bag.bags arnt usely used as theres a contamination risk? and catheters are nasty(dont want that for dd4 at all).aaargh!!!!!help please, any ideas????
