Unfortunately, she may feel unable to face you because of your baby. I would say it is good to keep leaving or sending messages, just so she knows you are there for her. When you do manage to get together, at least at first, you should probalby go alone. I am sure she doesn't begrudge you your child, but it is often hard to be around babies for a time after you have had a loss.

Just be as gentle and caring as you can. It is good for her to know you are there if she needs you.
