hi Lucyjones
you should query the shepherd's pie, if it's not meat then it's quorn or similar which they also shouldn't have so young. I'd leave written instructions about what they can have and say if in doubt don't give anything except fruit, veg, babyrice, milk. and keep asking them what they are feeding.
with my other dds at about 5-6 months, they fed something like: 7am milk, 8 am solids, 10am milk, 12 solids, 2pm milk, 5pm solids, 7pm milk. Maybe boiled water with the meals. Do you have a good weaning book? Annabel Karmel is quite good and gives timetables and loads of suggestions of what to feed at different times. I have a very nice veggie one too which does the same but all veggie recipes.
