answering "no" to "do you want [nanny] to come and play tomorrow?" - how seriously should we take it?

[Tutter]

mothers help/nanny started a month ago in preparation for ds2's arrival (was born 12 days ago)

ds1 (aged 2.2) seemed to get on with her ok to begin with, but less so recently - particularly since i brought ds2 home

he rejected her most of last week and says no when i ask him if he'd like to play with her tomorrow. should i be concerned, or is this to be expected given recent changes do you think?

NICE Tutter

well done

unfortunately 2 year olds say no to everything but you meant well
