Sleepy babies are really hard work at first. Luckily it doesn't take too long for them to start waking better for feeds.

How many feeds is she having in 24 hours, and how many wet and dirty nappies? This should help give some clues as to whether she is getting enough or not. Also, does she wake for every feed or are you needing to wake her sometimes?

You have tried many of the tricks for waking babies up. Some mums also find that a cool facewasher brushed over the baby's skin can help too, and another trick is called the doll's eyes method. With this you lay your baby on your legs, then sit her up, then lie her down again, then sit her up. Sometimes this can work well. Babies can also feed during their light sleep cycles, so often with these sleepy babies, feeding while they are asleep can work well.

The more milk she gets, the sooner she will stop being so sleepy, so keep up the great work with trying to get her to feed.
