6mo waking during the night, help!!

[tommyspud]

My DS is 6.5 months old. Up until Christmas he would go down around 7pm and sleep until around 5am wake for a bottle.
He has now started waking anywhere from 2-3am and babbling and generally making noise though not crying. If we put him in bed with us he will go back off until around 5 again (which we have been doing to be honest as we have 2school aged children and quite frankly are exhausted!!)
He doesn’t go back off on his own, though we can put him down awake at 7 and he goes off no problem so I don’t think it’s an issue being in his cot. Has anyone had experience of this and what did you do?
I’m getting conflicting advice from my mum to just let him have the cuddles as he’s only a baby etc whereas my DH thinks we should be trying to break the habit.
I’m very conflicted as I’m really tired and would love for him to not come in our bed every night and sleep longer but just don’t know if I can face sleep training! My other two were good sleepers by this age as in they’d do approximately 10 hours per night unless they were poorly.
Thanks for any advice!

Sorry just to add he doesn’t have a bottle in the middle of the night so it’s not a hunger issue either.

My baby is in general a very good sleeper but he has periods of not sleeping so well....generally put down to teething, growth spurts etc. I tend to just try to get through them. However, I never lift him from his cot when he is wakened through the night (he’s never crying, just babbling or screeching or cruising the cot). I just go in regularly to try to resettle (baby takes dummy) and he will fall asleep again. Mainly quite quickly, other times takes about half an hour. He is never in distress but I’m a firm believer that babies should be in their own beds (could be controversial on here). However I have one child and this may not be practical for you. Around the same age, I had frequent night wakenings and just took this approach. It settled back to normal sleep pattern each time and then we had another blip, usually coinciding with new tooth emerging, new skills being learned. Not sure if this will be any help but hope you find something that works for you.
