My 1y2m baby still can't sleep thru night. She will wake up 3-4 times at night. Try comfort her while she is crying. But she keeps flipping up my shirt and insists want nen nen to suck for comfort. I'm really tired. What should I do?

Some kids don't sttn until 2 or 3. Every kid is different. She will sttn when she's ready. That said, there are ways to help her sleep better at night. Things like keeping the room dim, having the same bedtime routine every night, giving her a bath or something soothing before bedtime, etc.
