10 week old sleep

Chelsea

My son apparently finished is 2nd leap (it was a struggle) but the last few days - he’s been sleeping 10pm-6am straight , then feeds and goes back to sleep. I’m crossing my fingers this is normal and becomes a habit long term. Does anyone know how long is too long for a baby this age to sleep? Lol I found myself waking up periodically because I was concerned . 🤦🏽‍♀️
