Safe sleep advice with toddler and baby

[PuzzledOfPuzzledom]

So, I know the NHS, Lullaby Trust etc all advise that a baby should be kept in the same room as you for all naps and night time sleep until they’re six months old. I’m sure there’s good evidence for why this is safest so I’m doing my best to follow it, but....

AIBU to ask how on earth do parents of more than one child achieve this? I have a young baby and a toddler and I honestly can’t work out how we can all be in the same room and keep it quiet enough for the baby to be able to get to sleep. My toddler is pretty quiet and calm for his age, but even so it’s not realistic to expect a two year old to keep quiet or not run around for hours every day. If the baby is asleep she can stay asleep through quite a bit of noise, but if she’s trying to get to sleep then anything louder than normal conversation will disturb her and stop her nodding off.

I feel like a completely useless parent and I’m sure I must be missing something obvious as I know other people manage this. AIBU to ask how people do it?

Be in separate rooms while she's going to sleep and then be in the same room once she's asleep and less likely to be disturbed?

I think the advice re. sleep is that babies can slip into too deep a sleep if in a room on their own, but the sound of your breathing helps them regulate their breathing that's why they should be in your room overnight etc. I think it's ok to leave them for a short while.

Does your toddler go to nursery at all and do they have a nap themselves? You could also get the toddler going on an activity while the baby is settling and go between the two, or have the toddler have some quiet time with you reading or listening to an audiobook while the baby naps

Who ever came up with this 6 month advice has never had to cope alone with a baby who needs quiet to sleep and a toddler.

Would going for a walk with them work?

I think the newborn will get used to the noise. I have 3 dc. 4th on the way. All 2 years apart from each other. There abouts and they just slept through the noise. Night time house was quiet but they would sleep theough tv the others shouting the hoover etc. Better they learn to sleep in noise than having to walk on egg shells everytime they nap!

i think i did what a lot of people did which was with dc1 you would whisper and tiptoe round the house but by time dc2 arrived it was a case of meh theyll have to get used to noise!
