Feel like you want to be there for your baby and can't because you need to go back to work. Then we have a lot of fear. You know, did I pick the right caregiver? Will my baby be safe am I going to miss out on all those important first moments but I love this author's advice that one of the things you can do is have your caregiver send photos during the day so you still feel involved. That was very interesting she said that some moms ask that care givers not send pictures. They don't want to feel like they're missing out. Point being very individual. One that works for you and that's just fine. One emotion that I think a lot of women have had. We have a lot of new moms in the audience. And moms-to-be.

Get some sleep, get your nails done, whatever it is, read a book. Whatever you need to do to recharge. Yeah, okay. Then finally, manyomen staying home after work simply not an option. So, what do you say to that? What's the -- if we have to do it, what advice do you have for us. It's the million dollar question. How do I balance it all? One of the most important things you can acknowledge and embrace is that you can't give everything 100% all the time. You are not going to be perfect. You know, give yourself a break. And then, you know, just work hard to give people what they need but know that it's not going to be perfect. Yeah, it's not going to be perfect. That is the truth and ten weeks in. Ten weeks in.
