Baby not sleeping at night

Try to feed him more in daytime than nighttime. Slowly reduce the time of breastfeeding in the nighttime. That helps in daytime feeds. They will become longer. Make a routine for bedtime that helps LO to know what's coming next. 15-20min bedtime routine. Whatever is convenient for you. Bath helps, calms LO down. Dark rooms make them think it's bedtime. You can also use white noise. But make sure to find the one which he likes. I had to try a few noises before I figured out which one helped my daughter to sleep.

thank you so much I am going to try it

For naps, if you can try, go for contact naps. I know people will say "no way," then baby will never sleep without you. But I believe in dealing with the problem right, and we will see what the future holds later. I did it when I was in your position. Currently, my daughter sleeps on her own in her bedroom alone. She is 20 months old. Just do whatever you can do to get some rest and peace of mind right now.

I feel you! My daughter is also 5 months old and wakes up every 1-1.30 hour. I don’t want to discourage you but I do everything suggested and it still doesn’t help :( some babies just need more time I guess. Hang in there!
I like to tell myself that this phase won’t last forever and one day I’m pretty sure I’m gonna miss it. So I try to enjoy the process even if it’s hard 🙏🏼

It might be the four month sleep regression arriving a little late. Hang in there, it will pass!

Have you tried sleep training at all? 5 months is a great time to start doing it . I know it’s not for everyone, but only speaking from experience . I slept trained my baby and she sleeps her naps 45-1hr and at night she only wakes up twice to feed during the night. Which is normal for this age group. Look up Ferber method.

No suggestions just solidarity... pretty sure it's either teeth or a new milestone coming... or all of the above. Is he sitting yet? Could be he's getting ready to do something new...

Could be that dreaded sleep regression! My daughter went through it at 4 months. We sleep trained her at that point and within a few days she was sleeping through the night!

Thank you so much mamas, I feel much better and hopeful, I will try everything mentioned

If it's a new milestone, like sitting up by himself, get lots of practice during the day. A good feed before bed for a full tummy. When my LO at 18months went through another phase of waking up every hour I moved her back into our room to make it easier for me during the night. You can also try safe co-sleeping, sometimes if my LO isn't feeling well she will only sleep for longer periods if she's sleeping next to me.

And solidarity, sleep deprivation is soo tough!
My girl has never been a "good" sleeper. We've gone through multiple phases of waking up every 1-2 hours, split nights (awake for 1-3 hours in the middle of the night), fighting sleep so it takes 1 hour to fall asleep. We've tried soo many things.

Honestly, sounds like it could be a sleep regression with intervals like that. You have done a great job trying the things that can help, and I would just recommend being really consistent with bedtime (times and routine) also with how you handle wake ups. I hope it's a short phase for you🙏

I can imagine, he also fights the sleep and takes 1 hour to fall asleep, thank you

he is trying to sit by himself, I will make sure he has a full tummy before bed
