I had unders and have a 1 year old and was worried about looking after him. You will definitely need help that first week I didn’t lift my little one at all that first week my mother in law had him. By the second week I was looking after him on my own but I only lifted him when absolutely necessary and when my husband was at home he did everything for the baby. I was fine to cook, clean etc from about day 3 though. I think you will somehow find a way to manage but do try and get help and not over do it. I just sat on the floor a lot to play or cuddle the baby. Xx
