Could an exception be made as you are suffering from morning sickness, by allowing you to snack on something savoury like crisps whilst you are working? -It would afterall make you more able to to your job better. If the kids want to know why you are eating you could explain in a simply way about how some pregnant ladies feel queasy during pregnancy and eating salty snacks helps.
Explain to the head how badly you are being effected by morning sickness I'm sure he/she willunderstand about you sncking and being unable to go on the theatre trip. My cousin suffered really badly with morning sickness and found it difficult to work (she is in th RAF) they were very understanding and gave her quite a bit of time off. If it gets too bad I'm sure you won't be expected to keep working. Hopefully this will pass when you progress with your pregancy.
By the time you read this you will have probably had your first day back, so hopefully all went well. Please let us know.
