Re: advice: back to work, leaving newborn with babysitter..
Bhenjee, my sister had to go through a very similar situation. She had to leave my neice at home when she was 3 months old. It was very very very hard for her, she called 20 times a day to find out what was going on at home, what she was doing, if she ate, burped, diapered, sounds she made, etc.
Now, my niece is 2 1/2 and my sis has been home for over 6 months with her. It was a rough patch, they made it and now are absolutely devoted to my neice's upbringing only.
It happens to a lot of couples. They have to work really hard in the beginning to make sure their life is better later. The important thing is to make sure you dont lose sight of the most important thing: your baby.
