just before my first birth child arrived, I got the wobbles - what am I doing, I wont cope etc etc.
Likewise with our foslings - I was plagued with doubts and fears before they arrived...what was I thinking etc.
The first week or two with birth children or with foster children was difficult...lives turned upside down, adjustments to be made by everyone.
And yet, we muddled along for those first few weeks and gave eachother support until suddenly, it wasn't so hard. WIth current children, it was a lovely sunny day, about 5 weeks in, and the kids all had a water fight in the garden. There was great giggling and laughing playfulness, and I knew it was going to be OK. We had turned a corner.
Its OK to feel scared. Adjustments will need to be made, but you will be OK. Little one will be seeking attention for a while, but once you are settled, away from people watching and all those expectations, you will find a place for love. You may find it takes a while and it creeps up on you. But it will come!
