Husband has to be near his family constantly

Okay so I am 3 weeks postpartum with our first child .... my husband has to go visit his mom and dad at least 2-3 times a week And wants my newborn and I to come with him every time and most the time we don’t leave his family’s house until 9pm which is way to late for the baby! I have told him several times Nicely that one time a week is plenty but he keeps on pushing me ...

His parents are very stubborn and out spoken they even tell me to quit breastfeeding and swap to formula cause it’s easier for everyone else .......

His mother has been hinting constantly to watch him over night which is a big NO he is only three weeks old!

They say I’m way to overprotective and I should leave the baby with them and go have fun!

My baby is fun to me I love being a mom!

I try to give my husband the respect of dealing with his family cause he always does that for me but I feel like he’s never going to stand up to his parents for us!

What should I do or say??!!!
