Constipated baby

Lorena • Momma to 3 beautiful babies!🤍🤍🤍
My son is going to be a month old in 2 days he gets constipated and I was told by a friend to put Vaseline on a qtip and put it in the rim of his bum. I'm scared to hurt him but has anyone tried this and actually worked? I don't want to do it and have it not help him at all
