I co-sleep; only way for me to get to sleep after feeding. DH sleeps in the nursery and won't get up at night.

Can't help too much as DS is still waking a LOT, but a massage/aromatherapy specialist told me the lavender that sends you to sleep is bad for babies; therefore you either use a product you shouldn't or a baby product, which contanis stimulating lavender! Also, some babies are stimulated by massage.

I have started to introduce a bottle of hungry baby formula at night to fill DS's tum - he will go for a bit longer, but not too much longer. If it is just hunger it may help you. I didn't want to give bottles, but I also want sleep and had been running out of milk at 3am before I added in one bottle, so it's worth it.
