New mom...need advice and sharing?

I'm sorry you are having to go through this. I know how hard it can be to leave your baby and go back to work. If your daughter is crying like this with everyone except you it may be that she just isn't use to the sitter yet and that she wants mommy. Have you tried taking something that she loves to the sitter with her like her favorite blanket? Another suggestion would be to maybe give the sitter a shirt that you wear that way when the baby isn't calming down she can try laying her on the floor next to your shirt (your daughter might be able to smell your scent and be comforted by that). You could even do a trail run of that with dad. And yes babies do know their mother's scent as well as their voice. I have fed both of my kids and my daughter seems (especially around that age) much more attached to me. I'm glad to hear that you have started introducing the bottle and the sitter to her before you actually have to go back to work. I would try to nurse and then pump to try and increase your milk and if you give her bottle then try to nurse after pumping. pumps can't empty the like a baby can and that will probably help with the milk supply as well. As far as cereal goes...I would try to wait until she is at least 4 months. I ended up giving my son cereal when he was almost 4 months, but it was always a hit and miss thing and the only reason I started him so early was because I had to go back to work and he refused to take a bottle. He would go about 7 hours without eating. Lucky for me he was a really happy baby and he didn't seem affected by not eating at all. Hope that helps a little and Good Luck!
