How about a get together with other new mums to share the experiences of your new babies? No-one will understand better what you are feeling than the other new mothers you met and got to know during the preparation time.
This would be a good opportunity to use the new pram or buggy and to dress your new baby in some of the lovely new clothes and baby gifts you may have bought or been given. When you are in a group of other new mums, or with just one other, you can laugh together about all the little things that you are finding difficult; from nappy fastening to how you get bootees on tiny feet and how to put on a sleepsuit. Things that seem designed to foil you when you are on your own suddenly become something to enjoy defeating.
There is nothing like sharing challenges with other people to make it easier to meet the challenge and more enjoyable too. You will end your get together feeling much more positive about all the things that have been niggling at you. Spending some time together getting the hang of all these new baby things will enhance your confidence for managing when you are on your own.
