Return the baby to Stacey until she is "found guilty" in order to respect the biological and emotional needs of mother and baby.
Never administer the baby formula milk unless with maternal consent.
Hospital professionals must adhere to the established guidelines of support and respect of breastfeeding on demand.
Since I know nothing about the case other than what was published in the Daily Mail I wouldn't sign a petition asking for these things. Translator, yes. Legal assistance-that's down to the British Consulate at this stage. The mother will get the kind of legal aid a Spanish citizen would get, if she were ever charged.
My PIL moved to Spain and have always found the Spanish health care excellent, as have their friends. Even in their nondescript province, there were new hospitals and they got very good, speedy access to specialist care. Not that this is wholly relevant-there are always pockets of poor practice-look at the NHS.
There is just no way to know the full background. Like when the DM does stories about children being taken into care in this country. The parents give anguished interviews setting out a tale of woe, none of the professionals involved can speak out to give the other side. Occasionally you get the full story and it's a shocker one way or the other, mostly you don't.
Two weeks for a DNA test does not surprise me.
