It depends how far along you are how much baby can hear outside noise wise. We’re the same aren’t we at 23? Apparently it’s like 28 weeks but it does vary a lot online some say slightly before as early as 23 so can’t hurt to give it a go!Can you try white noise from outside the womb? I’d really like it if this baby would go to sleep and let me sleep! Seems to have woke up and doing gymnastics in there.
