hihi, same issue ocurred to me too. My in laws (dad n mum) have 1 5yrs old boy, 1 15mths ger, and mine 13mths. My father in law will do most of the housechorus, will help to boil water, put water. wash baby clothes,etc. While mother in law will be the 1 looking after.
But in the end i choose not too, not becoz my in laws are not good, but dont think they can juggle.
But i do tout of the prob, like who to fetch and if both baby cried, who will she carry first. Sorry for being selfish, but is my first boy so of course i want the best and all attention on him. Knowing that he is in good hand, then i can work with ease . Before i gave birth, over the wkend i will be at the place, and saw how attached is the boy and the ger to my mother in law, coz they also stayed at her house.
After giving birth, know that my baby is 1 that cry super soft and very well tempered, the more i dont want to put him with them, coz sure kanna bully hahaa!!!
I m fortunate to have my mum still so that is my alternative, dont wanna to scare you. BUt do consider the convenience, weight the pros and cons, must impt your baby is in good hand =P
