Well, DH topped up with EBM in Tommee Tippee bottle - we used the medium flow teat since when I expressed the milk flew out of me.
DS3 had about 30mls and then gave up. Promptly woke up again at 1.15am - about 3 hours earlier than he has been doing when we didn't dreamfeed! He did sleep till 6.15 after that so can't complain too much.
His feeding pattern has been a bit off though with a cold so will wait till he's over the cold (as if! with two germ infested older brothers he's currently a week on, week off with the snuffles...) and try again
