Congratulations to you both mate.
I would suggest that you try to identify a local Filipino shop if there is one near to you. Not sure where in kent you are but if you are near one of the big hospitals you will, for sure, have some pinoy near to you. If you see one you can ask where you can purchase ingredients for Rose to cook home foods.
Rose is coming as the weather is improving, so showing her walks to the local shops should not be a problem. I would also ensure that Rose will have access to the internet while you are working so that she can keep in touch with family and friends.
Apart from that just enjoy the fact that you are together finally. Do remember though, that the adjustment may take some time. Particularly, in terms of Rose understanding local accents, wanting to talk to people, etc.
All the best.
