Hey girl ? We're three months in and our son jumps at any small noises when he sleeps. Sometimes he gets scared by some movements. Everyone says "he's just a little guy" but it really annoys me. I don't talk loudly with him, and when the baby cries, or someone talks loudly, he gets scared ? Will this pass with time or do we need to see someone about it?
