STTN 12 weeks

Hello! My LO is currently about 12 weeks old and he recently has started to sleep through the night (last feed 9-10pm, and next feed 5–7am). Is it safe/healthy for him to do so? Or should we wake him up to drink? He sleeps with a pacifier… Diaper outputs are still normal, and daily intake is still within range for his weight. TIA!#firstbaby
