I need to vent

So I’m a new mom! My son is 3 weeks old and I feel like my husband doesn’t help me out with him! I’m the one who wakes up at night and feeds him changes him and puts him back to bed! I’m the one who holds him throughout the day as well! Well my mother in law helps out she stays with him so she could have me get some sleep. Like today from 8pm-3am he’s been in my hand and I’ve literally tried everything fed him changed him burped him put warm olive oil on his stomach in case he had a tummy ache and he wouldn’t sleep and he wouldn’t stay calm and seeing my son like that actually made me cry I told my husband instead of getting up from his sleep to help he just turned around in bed and went to bed! Like I’m not the only one who made this baby you did too. It just baffles me..honestly! During the day and night , all in all he holds him for about an hour total. Like I need help with him. He’s not only my son...he’s his too. This is my son.
