Looking for some advice on sleep training

[mabel12345]

My girl will turn 6 months next week and I really need to put sleep training in place. As a newborn she would sleep fine, she would wake up just for feeds and go back to sleep in her ‘next to me’ pretty much straight away. At 3/4 months she would only wake up at 3 and then 6am and then she would sleep until 7 or 8. Everything has changed when she turned 5 months, we decided that it’s a good time to put her in her own room in her own crib but she would just wake every half an hour..every time we’d go up and soothe her, as soon as we come back down we would hear her crying loud. And this vicious cycle would last for around 5 rounds before we just decide to put her in bed with us (as we’re both super tired). Even though she “won” and found herself in bed with us, she is still waking up every hour so we need to soothe her, boob her or shush her to sleep.
I really want my husband and my bed back and I’m just looking for some advice on how to start to sleep train her to stay in her crib and sleep for at least couple of hour stretches.
Thanks in advance!

Before thinking about sleep training I'd be looking at the full picture of sleep. How much sleep does she get in the day? When are her naps? How do you get her to sleep for naps? Where does she nap? Usually wake ups overnight can be reduced by altering day sleep. Also how is weaning going? Could be she needs a bit more to eat to keep her nice and full before bed so she's not waking up for hunger.

Agree with the above, waking every 2-3 hours is "normal" but every hour suggests another problem. Could she be overtired? Should be having about 4-5 hours daytime naps (split into 3). If she goes to sleep easily and wakes up happy after naps that suggests she is getting enough sleep.
Other than that I'd start by introducing a comfort blanket. And give her chance to self settle - don't rush in but leave 5 mins of crying at each wake.
