Rebecca - Does Caitlyn sleep for long stretches in the day? If so then she will probably wake a lot at night. I wake Kieran if I have to for 3 hourly feeds during the day (that's three hours from the start of one feed to the start of the next) and get him to stay awake for a little while after a feed (sometimes this is hard!). He pretty much wakes up on the 3 hour dot to feed, but I usually have to wake him by the afternoon. I followed this principal (based on a book recommended to me) for Joel and he started sleeping through the night by 5.5 weeks (8 hours between feeds). I am hoping for the same success this time!

Saffi - It is possible because Lachlan is sleeping so long during the day that he may be having his alert time at night instead. I am no expert, but it is just a thought! The book I use recommends a feed/wake/sleep cycle during the day which helps establish good night sleep. I know not everyone likes to go by a routine (mine isn't that strict, I play it a bit by ear too), but it works for us!

Viv - I hope you get some decent sleep today!
