Oh, I hear you!
DS had colic until 5months. Hated the car - would scream blue murder - so any suggestions if 'just drive him around until he falls asleep' were just unwelcome nonsense. We tried everything, including lactose-free formula (whatever it's called).
He got better at 5mo when he started crawling, and I don't remember when we put him in a high backed booster seat in the car but fuck me that made a huge difference! He started walking a little before 9mo and cheered up, but then it was Benny Hill chases EVERYWHERE - house, street, museums, park, supermarket.... He wasn't a sit-and-colour toddler, he'd finger paint for 5 minutes thatd be it, no interest in sitting watching TV, having a book read to him. Just action and chaos - so we did activities with him: mostly park, puddle jumping, chasing seagulls on the beach. He had a little sit-on motorbike you pushed along with your feet and would scoot 100mph. When I bump into people from our old neighbourhood they always ask after ds and comment on how they'd watch him fly round the park (he's 14yo now!).
I don't think he liked being a baby, and with stomach pains, wanted to be up looking, moving, running, independence. DH and I would get him involved in everything - cooking, loading the washing machine, pairing socks, tidying toys, gardening - I drew a fire, in chalk, across the garden fence and ds would spend ages "putting it out" with a watering can 😆
So I'm suggesting activity after activity, lots of love and kisses and hugs, swallow frustrations. But don't ever compare your child to others - that way lies madness. DS is a potato only when asleep!
I send ((hugs))
