E: 6 pm
A: bath time, massage, jammies
S: usually in crib and asleep between 7:00-7:20
Does this work for you? Is he falling asleep without a feed? Is his weigh gain ok?
If that's how things been then I would just let be, don't fix it if it's not broken, lol.
If you want to stop with the cluster feeding then you can offer a feed before BT and just not wake him up for that cluster feed.
TBH, your nights look great for having such a young baby and I don't know if I'd change something IIWY.
Maybe when he is a bit older, when his A and S are different then there will be anyway a BT feed.
