Good day everyone, I wanted to ask mothers, do your second children hit their heads? My two children, my eldest son and my second daughter, she has already hit her head three times. The first time she learned to roll over, she fell off the sofa. The second time she put herself on the bed and while changing clothes, she fell on the floor for just a second, bent down to take off her pants, and then she bumped her head hard, she cried a lot since then we sleep on the floor on elevated places, I don't lay down on the floor anymore today she was lying on the floor turned away for a minute to look at her phone, my son threw a lamp, and the lamp is heavy, thank
