the new era

I got an offer from a very reputable medical device company.
The me side of me is very excited and happy; the mom side of me, however, is wary and hesitant. This is going to be a new era for me, and for us. I am going to become more independent from Arman and vice versa.
I am going to resume my professional life, and grow mentally and professionally. At the same time I am going to miss Arman like crazy.
Arman is going to meet other children every day, play with them, eat with them, babble words with them, and learn with them. He might miss me for a while. Eventually though he will grow out of it, I am sure. He will start to find this as a new routine in his life.
I, however, am never gonna grow out of missing him. That is only my feeling and I have no proof for that but I am confident.
This is the worst thing about being a mom so far: having to leave my baby with another person.
