It would also be good to see if there's someone - a brilliant mother - from her own culture who can act as an auntie… poor girleen sounds awfully isolated somehow. And maybe see if her local library has a mothers' group who talk to each other about bringing up their babies.
Here's a nice little video by a mother on preparing pureed carrots which also has a piece from the Health Service Executive in Ireland linked below - unfortunately, the video (and obviously the HSE advice too) contains written stuff which she won't be able to read. Can you direct her to reading classes too?
