I am wondering this too. I've seen the NHS doesn't recommend it but we still have multiple night wakings so I'm looking into anything that might help.
@Emily yes same here! And a 5 month old so desperate to find something that helps - we’ve tried everything else!
Yes, we use mighty supplements magnesium - it’s a bit pricey but it’s high quality and absorbs unlike the cheap gummies. Highly recommend it more for regulation and behaviour but I I’ve seen sleep benefits too.
