My son is in the process of learning to crawl and he keeps ramming into the dang sides of his crib. Better then my concrete wall though. Can that hurt him? I have crib bumpers on but there the breathable kind so it’s really thin because I worry myself to death about him suffocating in the middle of the night. He’s 7m old but he was born at 6 months. His actual due date was may 10th so his adjusted age is almost 4 months. ThaTs what the docs go by... I have a thicker set but like I said I worry about everything including this. His soft spot is on the top of his dang head... suggestions???
