Yes we have had the same experience - pregnant and enquired in November 2023 for a place intending to start around Oct/November 2024 and they said nothing until September 2025 at the earliest and weirdly enough they don’t take extra children even if people leave through the year as it “unbalances the age group”.
fortunately we managed to secure a spot at dd1 old nursery due to the relationship we had with them but it means travelling to get there and we had wanted something more nearby since we had moved.
even our local bright horizons has a huge waiting list. N family club wait list is minimum 18 months also - I don’t know how any first borns babies can even get a place in the first instance
it’s crazy!!
