Hi Blending, congratulations, twins are very special! I bf my two (having bf their older brother) and they were almost ebf, but, like Margetts, they each had a bottle of formula (probably only 3 or 4 oz each) in the evening just to give me a break. I used a breast pump while they were in hospital but never found the time to use one once I was out. Lansinoh was my best friend at the beginning!
In the early days all I seemed to do was feed and change babies, and do laundry - the amount of laundry was a bit of a shock, tbh! Mine were delivered at 34 weeks and I had to express while they were in SCBU for a fortnight, but we got things established quite well. Once home, I took a slightly different approach to Margetts and decided that unless they were both awake and hungry at the same time, I'd feed each seperately on demand and not wake the sleeping twin - I realise that this extended the amount of time I was feeding in a 24hr period, but figured that it gave them some one to one time with me. At night I would have the feeding baby in with me and feed lying down until we both went to sleep. When twin 2 woke up, I'd put twin 1 back in his cot, asleep, get twin 2 in bed with me and then feed him to sleep. This was repeated over and over in the night, but I decided that this would give me the most amount of sleep. That said, it did feel like there were some nights when it was non stop, which was a bit of a shocker.
I had a major wobble at 3 weeks, deciding that I just couldn't continue, but this was when we introduced the evening top up and we continued just fine. I was given a feeding pillow by my friend and it was really useful for the times when I fed them both together, but the rest of the time I had either of them in the usual crook of the elbow hold.
I was advised by my hospital to stick to one breast per baby per day and then swap to the other one the following day, which meant that each got a go on the more productive breast every other day. This worked really well for us, and I continued it through the night so would lie on one side for t1 and on the other for t2 when they needed feeding.
And the eating !! I returned to WW after their 6 week check and lost weight really easily, because I got almost double the daily allowance of WW points, as they gave me extra points for each bf baby! Lots of chocolate was eaten but the weight fell off. (Unfortunately it's all back on now, adjusting to eating less onvce they were weaned was really tough!)
Good Luck, ignore the naysayers and ultimately, as long as your babies get fed and everyone's happy, it's irrelevant whether it's bm or formula (although I have to admit, the thought of sterilising two sets of bottles didn't appeal to me!!)
