Husband was building three year old’s bike. Three year old was trying to get on said bike and not giving DH much space. DH lost his patience and lifted son up on quite a forceful manner, shouted that his behaviour was unacceptable and set him on the back step. Three year was very upset. I went outside to comfort three year old, brought him inside for a cuddle and reassured him that Daddy had lost his patience etc. but I am really not happy.
