when bb is young, can't talk.. it's better to have an elderly around to help 'jagar' the maid as well as 'coaching' the maid as young toddler can't speak well.
I have maid since my girl was 8mths.. mil was staying with me.. until the maid is trust worthty, mil is free to go...
now with new maid (1mth old), found tt she loves my kids.. cheerful (unlike previous one.. always sunken face).. I still keep my finger crossed.. mil will be coming over in May.
