Yes that's understandable. My sisters son was the same (she lost his brother at 24weeks). It was hard for him to get excited and didn't really expect a baby I don't think until he was visiting him in hospital after he was born.

My boss guessed yesterday that I was pregnant which is kind of a relief as I didn't really want to spill the beans. She was very good about it which was good as I was worried how she would feel with me taking leave again. I don't know what I'll do, I don't know if I should resign and just pick up the odd casual shift down the track. Or try and take a year off and just do 1day a week. Realistically with 5kids I don't think I can manage doing more then 1day for that first year or 2.
