Thanks for the feedback, very reassuring. I presumed/hoped things would naturally develop further so I look forward to the next stage. I am lucky in that the girl is already starting to sleep 5-7 hours some nights so I may feed the boy twice before she wakes up (although she suprises me once a week with an off night) and have even managed to get 3 hours in one go on occasions!!
Egg; I know exactly how you feel, my dd had one of those off nights I mentioned last night and took an hour to feed and half hour to settle. I get frustratd for a few mins amd then remember that they are only 7 wereks old so shouldn't expect them to perform at every feed/day.
To answwr your qu; in the day they are now just about managing to last 3-4 hours, although I do still top up every now and again especially the boy who requires more.
For the past week we have tried to stick to feeding in the day around 11, 3 and 7 to subtly encourage a regular pattern, however, in the night we still feed on demand.
We decided to not feed them together at night because the girl sleeps more and if we did wake her up she would fall asleep whilst feeding. If they wake up at the same time my dh will bottle feed one with formula.
In the early days I would get uptight planning the next feed time before the last one has finished, I am a little more relaxed now, I think it comes with time.
Congrats Egg; it's so wonderful having twins!
