Lo is coming 5months. Still need to be rocked to sleep. Should i start sleep training ? or he will slowly outgrow it ?

we shouldn't be depriving our kids of their sleep just like how we wouldn't deprive them of food. disrupted sleep at night because they need you to help them fall back to sleep is unhealthy and not beneficial to their development. sleeping is a skill that our babies should learn. it's the most difficult skill but once they learnt it, it's for life. he will only sleep on his own when he turns 2-3 years old.
