I brewed an Old Ale around this time last year as a beer to be kept until our twins were born in August. Took a bottle in to the hospital and cracked it the evening after they were born. It wasn't that good but has improved a fair bit with more time in the bottle. Will be keeping a few around for the 1st, 2nd and maybe beyond birthdays.
We don't have the third one but the best piece of advice I can give you is to do all the feeds at the same time and get them into a consistent routine. Don't believe the people who tell you that they never sleep at the same time. Our twin girls have slept from 8-9pm until 7-8am (almost) every night since they were 3 months old!
