our dds are nearly 3 and just 1. the youngest has been a complete pickle and i am only just weaning her off the evening breastfeed. but she is fine at night- now wakes only very rarely indeed if at all when at home. she isnt brilliant when away from home for sleeping purposes. both sets of our parents are keen to have our eldest dd (briliant sleeper) for overnight stays. my view is they are sisters, they come as a package and they should both be welcome at their grandparents' houses. but i dont know if i am being reasonable or not. how will dd2 get to know them and their places better if she never stays over there? it is difficult for us all to stay as not really enough space....would you let them just take the eldest one until they ask for the youngest? my inlaws in partic show def favouritism towards eldest and it does wrankle sometimes which is prob why this issue has come up in my mind.....
