Fran cried immediately after (naturally) but I had her bottle ready and waiting and after a few sips she calmed down and went to sleep. She slept lots and was rather grisly, even waking at one point and crying for about 10-15mins (which is extremely unusual for her) sounding very distressed before going back to sleep.
She didn't have any raise in temperature or any other symptoms and as she was sleeping I didn't feel the need to give her any calpol. She was back to her normal self the next day and has been fine since.
The nurse told me some mums give their LO's calpol before going in, some straight after and there isn't any right or wrong, so just go with what you feel is best xx
