you can, every child needs to be changed, and its easy to spot when a nappy is full of urine........it bulges in the front....
does nanny do all nappy changes for both families all day, or is there some sort of confusion going on if you/grandmother do it occasionally?
you can ask for nappies to be changed at certain times every day, a timetable of sorts, which nanny can follow.
how many children does nanny have care of each day?
just two toddlers? does she look after baby as well?
toddlers are messy and do need to be watched all the time....so it is hard to keep on top of things sometimes.
if your child is not recieving the same standard of love and care from nanny, this is a serious issue, are you sure this is the case? sure that differing personalites of child mean that nanny is changing her attention/methods/ distraction/play for each childs needs?
for isntance, is she just making sure that other child isnt running off and breaking something in your home?
if you come to that conclusion you may need to find another form of childcare./another nanny.
what are both households 'rules' very different?
does nanny plan outings/ games/craft/ cookery or other fun times for both children? does she have that freedoom?
is she trapped in house with grandmother and you watching her cope?
but really you need to sort out the other family not paying their way. and i do hope this is a very shoot term thing.
this is not your nannys fault, so dont put resent your nanny for this...
also, having been a nanny share in the dark ages, before my own kids, i can remember the trouble i had keeping two sets of parents happy, and their own rules , values and concerns....add extra grandmother, and all those adults watching her cope with two families kids........not an easy job.
also, for you , at home with new baby you are bound to feel worn out, i think the other family are taking too much for granted by you having extra kids in your home, when you need to recover from childbirth,etc. its stressful, sleep deprived time, with wobbly hormones.
