I also feel bad when I need to put my son in his play room when the house is too messy sometimes we don't have a choice but to put them where we know for sure that they are safe. if you can avoid not making them cry its better for them psychologically aswell. I know its tough its all a learning process. If they cry for too long they feel abandoned and its not good for them. They're attached to us so we have to see how to make everything work so that they can grow up to be healthy emotionally, mentally, physically.
@Lagringachilena I do always stop what I’m doing and pick him up when he cries. I try a pacifier to see if that’s what he wants, especially late at night. If he keeps fussing I always pick him up and give him snuggles and a bottle of hes hungry
You're experiencing mom guilt and it's perfectly normal. If you set down the baby and he's fine and chilling i see nothing wrong with it. Babies are gonna cry, no matter what you do so do what you gotta do and then snuggle the baby. It's also okay to not do anything all day and just be with your baby.
At 3 months old its important that they don't cry as much so that their belly button doesnt pop out. Someone else will have to wash the dishes or try to wear the baby in a wrap while doing things.
