I hate to sound so blunt but… Get used to it!
They are your husbands family (your baby’s grandparents/uncle)and just like you would want to spend time with your family…your husband will like to do the same. It may be troublesome for you to care for your baby, take care of your in-laws, and keep your dupatta on simultaneously but it’s a sacrifice you have to make. It’s not like you will be with them all your life and it’s not like they will go with you everywhere all the time. Ask your husband to help you out to ease any ‘burden’ (which you shouldnt be feeling) you may feel. Besides it’s not like this is your honeymoon! Consider it a family vacation and enjoy it.
Just be patient and do it for your husbands sake.
