I just moved here in January and I must say I wish I had friends like both of you !! I've heard twin moms suggest that when visitors come over to "help" that the best way they can "help" is to do some dishes or load of laundry, etc. Bring a meal with you when you come, or see if she needs milk, bread, etc.
During this time it is important for the mom to tend to the babies and get into a routine of how to feed and change them both. I've heard coming over JUST to hold the babies all afternoon isn't helpful. I'm wanting my babies to co-sleep -- meaning they will sleep together and like in the womb be used to being near each other. The reason for this is to feed them and hopefully nap them at the same time. If they are feeding every 2-3 hours especially in the early days it is easier to do them together or I will be doing it every hour on the hour !! Yikes. Be prepared for the babies to be in special care (intensive care) for a couple of weeks -- often they are early and the babies need support. Mentally I think every twin mom needs to be prepared for this.
