Honestly it’s unique to the baby and the parent. Some babies sleep through the night at 3 months and stay like that. Most have regressions and struggle sleeping through the night up until age two or later. If you do some sort of modified cry it out when she is older, she won’t need to nurse through during the night. They nurse mostly for comfort after a year at night (like for teething) but you can soothe her in other ways but continue to nurse the rest of the day. I don’t believe kids are more clingy because they are nursing. Usually clingy comes more a lack of security or just a phase. Nothing to do with nursing.
