I am working out of the home too. I am really frustrated by this whole mother-guilt thing I see amongst my mama friends.
I think you should try really hard to let go of your guilt, just don't swallow the line.
If you have to work, then do what you have to do. Guilt is for when you have a choice, and you choose the wrong path. You don't have a choice, you are doing what you have to do to keep your family clothed, fed, and warm. You're a hard-working "taking care of business mama", not a neglectful mama. Banish the guilt. Gonzo. Let it go.
Let's try a new perspective. Try and think of your caregiver as a parenting partner, not a replacement. Listen to your heart, if you are not comfortable with the care, insightful, intuitive mama, pull your child out today! Have failth that you will find other options.
I am on my second homecare caregiver, I was an guilt-ridden emotional wreck while my son was in insufficient care, while I was looking for someone new. What a waste of energy that was! I made a few phone calls to homecare agencies, and poof, started with someone new the very next week.
My new caregiver (for the last six months) is not perfect, she does things that I would not do, but she loves my son, is very gentle and kind to him, and he loves her.
If you want to raise your child exactly the way you want, then you'll have to stay home. But since that is not an option for you, let it go. Just let it go. Or, conversely, figure out a way to do it. Maybe a radical lyfestyle shift is in order. Join a commune, move back in with family, sell your possessions.
Choose to be happy, or don't.
Here is a hug for you (()) We all struggle with this everyday. You are not alone. Peace.
