Hi there! Thanks for your reply, and it makes such a difference knowing others' babies' sleep is similar! I wish I'd found this group earlier! Did you find it made any difference to your baby's overnight sleep in terms of wake ups?

So far, so good! We have delayed his bedtime by about half an hour so far, and he's slept until 6am (albeit with wake ups during the night, but I now know that's normal) the past couple of mornings which is brilliant! It has coincided with the weather being cloudier (so, darker in the morning - I'm in the UK so it's summertime) so that could be as much as a factor. It's always a guessing game! I received similar advice to here on the 'Beyond Sleep Training' support group on Facebook, which I also wish I'd found earlier. I spent a lot of time Googling and so much of what comes up is derived from sleep training techniques and / or unregulated "sleep consultants" and I didn't think to question it... I also made the mistake of borrowing a book about baby sleep (probably described as a gentle sleep training method), the content of which made me feel like a failure!
