Nellu,
Actually my boi is taken care by my IL too. So really at times, juz hv to 'see no evil, hear no evil'. It's happier this way. You know, whenever I hv abit more time to chit chat with them, I am always given surprises .. such as, oh, bb actually knock his head a few times on e ground & cried (happen quite some x le) or MIL giving bb rocher choc. Wat to do, dun give oso give le. I can oni reply & say, oh, bb cannot eat choc la. Than cook up some horror stories of bb got bad allergy from nuts, choc etc etc.
Tho' my examples may not be as 'unbearable' as yours .. but really, tink of the bright side lor. At least with grandparents, you know bb is safe wif some families member. Infant care & all, they are strangers afterall. I was thinking abt infant care for awhile, than decided against it. Maybe when bb is older & can speak & express, than childcare will be an option.
