My twin girls just turned 2. My advice is to feed them at the same time, to help get them on the same schedule. If one wakes up in the middle of the night, wake the other.
Also, ask for help, and don't be too hard on yourself if things aren't going well.
Finally, I when my twins were about 6 months old, I found out there is a ton of free stuff out there for parents of multiples. I wish I had known sooner so I could have taken advantage of it more. I wrote what I got here:
While i agree a schedule is key with twins, dont expect or force it from day 1. its important to follow your instincts and tbe babies cues like you would a singleton. Line up help for your other kids, meals, etc. write down who ypu fed/changed and when or you will forget! take lots of pics because with 2 its a bit of a blur at first. srt talking about a plan for nigjttime now. are you each taking 1 baby, alernating feedings, one handling the big kids and 1 the babies if yhe bigs arw still waking, one doing a ew hours then switching? make sure your husbamd agrees to a plan and sticks to it. no one but other twin moms will really get it, so find someone with twins you xan talk to
