I let my baby cry it out

Honestly, he was probably overstimulated by then and needed a break from your overworked nervous system. You’re ok - you did nothing wrong. He was safe and not neglected since you were right there watching.

You’re doing great! I hope he gets a good nap in.

I would try laying down and nursing him to sleep and if that doesn’t work then take him for a drive on a highway or where you are driving nonstop.

It sounds like you did everything you could to help him, which makes you the opposite of a bad mom. 3 months was a rough one for us too, he was starting to take in so much more of the world and he was constantly getting overstimulated buy everything, us included and really struggled to sleep.
It will get better, and you did absolutely nothing wrong.

For anyone voting no, do you have any suggestions? I tried all the things that usually work so I would love to know

the only thing that works 100% of the time for me is going for a slightly bumpy walk with her in the pram with the hood thing up

right I voted no, because I literally thought you'd just put baby in bed and not tried any other methods first!
he was fed/nappy changed and in all aspects cared for- he was probably over tired and needed a few minutes of stillness/quiet to settle/sleep. to date I have done exactly what you have described with all my children and usually within 5/10minutes they settle if it is infact tiredness - keep going momma ❤️xx

I said no because I m sure it's never ok to let a baby (or any human being) crying on his own... Yet you did everything in your hands to try. I think you were trying actually too hard. Sometimes babies and bigger kids (even adults) cry just because we need to and it doesn't mean you have to fix it. Of course your nervous system is looking forward to fix it so it's very hard. When it just doesn't work, you can hug your baby for a while and work on your own system. Relax yourself, breathe in and out, pit out some relaxing music in your ear so you won't ear the crying that much. And hug your baby. Your baby naturally will calm down being inspired by your own calm. If you are nervous trying to find out, your baby will also copy that. Sometimes we just have to hear the crying and hug them while giving them the key to calm down by doing it ourselves. Hope it helps 🤗

As much as letting your baby cry was a thing back in the day it’s actually not recommended as your baby is so small they are unable to self soothe. The reason he would’ve gone to sleep would’ve been due to high stress levels in the end the mind shuts down. This is okay as they get abit older 4-6 months and you are definitely not a bad mother because you tried your best! Never ever blame yourself when you tried! Is there a possibility he had wind?
Have you tried a white noise machine?
I used to have to heavily bounce up and down at the end of the bed, I know it sounds stupid but it worked! I’m not saying this is going to work for him, but try to exercise all of your options like you did or try things that might even sound mad but are safe of course. Well done mummy, keep on going🩵

I’m not against sleep training. But most recommendations are for babies over 4 months.

Personally I think 3 months is too little to sleep train

What Lillie said ! good luck!
