My Toddler Has Just Started Stuttering

My Toddler Has Just Started Stuttering My 3 year old son has recently begun stuttering when he says the word “We” or “You”. He will say we 6-7 times and then give up or say we once and then just stop trying. He thinks it is funny as it is an impulsive thing he is not consciously doing. He will laugh about it which I have encouraged as I don’t want him to be upset or stressed out about it. Is this how stuttering begins or is my son just going through a phase. My phase stuttered when she was younger but has worked through it and rarely does anymore. I am not worried yet, just looking for some guidance, or if someone has something helpful to say I am happy to hear it. Thank you
