My twins are all grown up now but here is my wisdom - or not!
The earlier a woman knows she's having twins, the bigger they are at birth. That's because you will rest more, eat better, demand less of yourself and protect those little ones fiercely. No pretending this is time to play the hero and carry on as if nothing's happening. This is special.
Your babies grow when you are sleeping or resting. I put my feet up for an hour after lunch every day.
As you get bigger there's less and less room for your stomach in there, so make every mouthful count. Go for small, nutrient dense meals and snacks and graze rather than sit down to three meals a day. You have no room for junky foods.
You will get more scans as measuring the bump won't reveal whether both babies are growing. That's fun and special, too.
Swimming gently is a great way to take a break from carrying the extra weight and very relaxing, too.
People may tell you 36 weeks is 'term' for twins but it doesn't have to be. I just scraped into week 39 with mine and they were 6lb 10oz and 6lb 13 Oz.
If your body is struggling to nourish two, nature will prioritise brain growth, so their little arms and legs may be skinny at birth.
You can successfully bf twins and it is the best weight loss strategy ever!
Good luck and congratulations.
