Working mums, How to take care of kid while at work? I am little afraid of entrusting him to some one else.

By someone else, do you mean nannies or child care professionals? If it bothers you so much, are there any other options? Maybe your parents or in laws? I'm sure they will take care of your child well and you can have ease of mine. Alternatively, before hiring a nanny, you could conduct thorough interviews and background checks so as to ensure the best for your child.
