Experiment with nursing pillows, which allow you to feed two babies at once. They will get used to waiting for their turn. Infant swings or vibrating bouncers can be indespensable. It doesn't harm the babies to cry for a short period. Don't worry about bathing the babies every day.
Some parents bathe their babies every other day or try getting someone to help during bath time.
Take a trusted person with you to help - visits to the Doctor can be hectic. If you enjoy dressing them alike, do it while they are little and enjoy it. As they grow older, dress them differently to help them establish their own identity. Be sensative if you have other children so they don't feel left out. These are only suggestions, so do what works best for you.
