dd2 is 15 months and still has a b/feed most mornings, partly through convenience (she wakes v early and I pop her in with us and latch her on) also I think/hope even 1 feed still helps her immunity. She has had 3 sickness type bugs over recent months but all have been short lived with no diarrhoea. I appreciate this may be luck.
I myself had severe d&v last night. When she woke at 5am dh did pop her in with me as normal, and did feed her as usual. However am not sure if this makes her more or less likely to catch my "bug"?
She will take cow's milk in a bottle no problem if necessary.
Btw I am very vigilant re hygiene, handwashing, wiping loo handles and door handles etc to minimise infection risk.
As well as the b/f, is it best to keep her "at a distance" for 48 hours. Obviously I can't ignore her, but I have restricted kissing to the top of her head, and given her to dh for cuddles more.
