I FEEL SO TERRIBLE😭😭

I was at soft play this morning with my son ( 13weeks) and my nephew (2years old) my nephew LOVES!! The bones off my son, and literally gets SO! Excited every time he sees him..

as he is only 2 he doesn’t quite know he has to be gentle with him, so when we were at soft play my son was lying just kicking around and my nephew comes running over grabs him in excitement and starts rubbing his face ( really really hard ) and picked him dummy up trying to literally shove it in his mouth. My baby started squealing as I thought he got a fright at first, so I picked him up and loads of hugs. It wasn’t until I got to the car when I noticed his ear was bleeding, and when I cleaned it down I noticed a cut. Now tonight whilst feeding him I have noticed a tiny bruise on his eye. I can’t stop crying, I feel terrible, I feel I have failed as his mummy, but he is only 2 and he doesn’t know any better! I just can’t stop thinking about my baby so vulnerable😭😭😭😭😭
