as i am a nanny, i am going to stick my head out on a limb and say that her methods are what i use, as do many other nannys, as does my mb (who obv has children)
and yes we get results
there are battles you let slide and others you fight, nice manners, sleeping through night, eating food etc
obv SN doesnt have children, as doesnt other childcare guru whispers gf and maybe if they do, then they may find their children are ickle pickles but they may have the perfect baby as well
nannies dont have that emotional tie which is why it is easier for us to get a baby sleeping through the night - we know that cc will work etc
one of my good friends is a fantastic nanny, and is now a mum, she cant get her baby 9mths to sleep through the night as every time he cries she picks him up - she knows what to do, and she knows she is wrong (if that is the right word and thats what she said, not me) but she cant help herself and wont leave him to cry - and they both end up in tears toegther she is a complete wrack as has no sleep and is shattered!!
she has asked me to go in and sleep train him and i said he will be sleeping through the night within 2 weeks - i have also told her to go and stay at mine, during the night/with friends/take sleeping pill etc so that she wont hear him cry
anyway i regress
sn isnt the devil. she just sets guidelines and if you follow them then life should get easier (remember it is the parents who contact her for help)
