My daughter slept through the night at 5 weeks doing 12 hour stretches. My son is 10 months and just started doing a 10 hour stretch for me. They definitely will sleep through when they are ready.
Duuuuuuuude, my child didn’t sleep through the night once until he was about 15 months old, and now he still wakes up at night about half the time. There’s good weeks and bad weeks. Today is my youngest son’s first birthday, and he hasn’t slept an entire night yet.
My son was sleeping through the night at a few months old after he got over the colic stage BUT then he hit like 16283937393957 sleep regressions shortly after. He’s been consistently sleeping 12 hours straight though since about 13 months old. My daughter is almost 3 months and she sleeps 7-8 hour stretches at night so who knows what she will be like 🤷♀️
My first two were about 2-3 months. This one was probably 5 months until it was a regular thing. Some nights starting at 1 month he did but it was just every now and then.
My son did. Slept 12 hours a night from 4 months on. Thought I was the baby whisper. Then my daughter was born. She turned 3 in May and still doesn’t sleep through the night every night. The universe is laughing at me. 😂
