Baby been in routine since 3 weeks old

Hello 👋 my LG seems to have been in a routine since about 3 weeks old. I always follow her cues, she’s a very light day time napper, she naps maybe 30-45 mins at a time at the most. She gets a bath at 7pm, bottle at 7:30pm then at 8pm she cries until I put her in the basket upstairs! She’s BF so she does wake for a feed every night at 1:30am then a feed at 5:30am but always goes straight back to sleep until around 7:30am. She is now 3 months old and it’s been the same routine since she was 3 weeks old, it’s like she knows when days and nights are! Has anyone else had a baby like this? I feel like I should be more sleep deprived than what I am 🙈🤣
