Cutting out a night feed ?

Any tips on how to stretch out my boys night feeds ?

He does three hours during the day.

I give him formula for his last bottle of the night around 9 and he does a good three hours for me. But then he always wakes every two after that.

He falls asleep when I’m feeding him so I feel like he just isn’t eating enough but he just won’t feed if he is asleep!

I tried doing a top up bottle which he would drink but he was so half asleep he just started gagging on it and spewed everywhere from it and woke up two hours later.

I tried resettling him back to sleep with a dummy to push his feed later, but he just wouldn’t settle. When I fed him he Dranks heaps because he was awake ! But then after the feed it took me a while to get him back to sleep. Usually he just stays asleep.

But he did go the three hours between the feeds that time.

I’m so lost with what to do 😞😞
