My kids are 6, not really babies anymore (but they will always be my babies). I am actually excited to just be having one this time, I dont know what that's like. Pregnancy is definitely different though.
I am pretty honest about having twins, its hard but you will figure out what works the best for you. I took advice here and there, but really took my own path in a lot of ways. Having a schedule was great for us, if you can get those babies on the same schedule. If they eat at the same time and sleep at the same time, that allows you more time to rest as well!!
