my kid doesnt cry much. He will have a rare tantrum but that's just part of growing up and learning to moderate your emotions. If you dont want a baby to cry, coddle them and treat them like the blessing they are, and slowly stop coddling them as they get older. If you hurt them, apologize, if they do something you appreciate like potty by themselves or they draw you a picture, let them know how cool it is and how much you appreciate it. If they want to help you and you cant accept their help, let them watch. Tell them "learning is very helpful! Thank you so much for learning. Please learn with your eyeballs only, not your hands. This is too dangerous for toddlers". If you want to leave them in daycare at church and they wont stop crying for you when you leave, do not reinforce this behavior by validating this behavior. In my honest opinion, if your kid is screaming and crying when you leave them in daycare, then you and the kid need to work on self growth and you should not leave them there to cry it out, it may cause abandonment issues. At the very least, other kids will see the show and it will stress them out and if they struggle with this themselves, they might start crying too and the issue spreads like a contagion. I don't leave my kid at any point when I go to church because the main reason i'm going is for toddler and I'm very untrusting of people. If you vaccinated your child very young or within the first couple days, your chances of your baby crying uncontrollably for no apparent reason goes up and you will probably be stuck with a colicky baby. Babies that cry alot are pretty common in first world countries due to overworked parents, woman not spending enough time with their babies, formula instead of breastfeeding, and vaccinations. Babysitters who are unvetted can easily ruin the fragile mind of a child.
