We have a 5 month old DD. She is a lovely baby, rarely cries. After the newborn stage she settled into a great routine with a cluster feed in the evening, another one between 2-3am and then a morning one around 6, followed by a nap until 7.30-8.
Those were the good times! Then we had the 4 month regression, and all went out the window. Now we seem to have a night time snacker and I'm knackered all the time.
Now she goes to sleep around 7 after a cluster feed (sometimes feed-nap-feed) and wakes up every 30 mins, sometimes she settles with pu/pd and a song, others need a bit of mummy dummy. Same in the night. She wakes up every hour from 3am until 7 to snack a little and then pass out. Around 7 she would have a proper morning feed
We are co-sleeping at the moment as the 4 month regressiom was bonkers. I want to move her into her cot (Snuzpod) but she wakes up every time we try to move her.
I'm scared we are creating really bad habits and also I'm supertired and cranky all the time! 
Any advice is welcome, although please understand that I won't try CIO, or at least just yet.
