Maternity leave in this country sucks, doesn't it? I know it's hard, but your little baby girl will be fine. At that age they don't have the separation anxiety. I was lucky enough to have 3 months of maternity leave, so I could wait and put them in at that age, and even then as long as they were changed and fed and warm and loved, they were fine. Their development is normal, they are happy and well-adjusted. My daughter is 3 and my son is 7 months. They love their teachers and bond with them as well. You will still be special mama, don't worry about that.
The only concern I would have is exposure to colds and other day care illnesses, so maybe you can be extra careful about washing your hands and your older child's hands between day care and home before carrying your baby? Perhaps load the car with your bags and then you and your older kid wash hands together before getting the baby. I would expect more colds if she's in day care so young, but that's about it. I would be stringent about vaccinating your older child against the flu, and ask the day care people about illnesses going around. These are the same precautions I took for my 3-month old when I had to put him in and my 3 year old was going, except for the hand washing. Maybe I should have done that, but I didn't.
