I have this same thing but at bedtime rather than mealtimes, if I try put my son to bed he throws himself around the cot for an hour shouting and giggling at the same time 🙃 past 2 nights his dad has put him to bed no bother 🥲
Oh its so completely normal for babies to be at their very worst for mum buy a little angel for literally everyone else. Your the safe space, they feel most safe and comfortable to let all those big emotions out around you.
