I’m so tired

I have 4 month old boy who is ebf.He was good sleeping before there will be times he will give me 4-5 sometimes 6 hours stretch of sleep.And he could fall asleep by himself but now everything seems impossible.Now he wakes up every two hours sometimes even before ,he have eczema so it doesn’t help he is scratching himself so much I put his hand in socks so he doesn’t hurt himself but he still wakes up.I tried to put paci and to move his hands from his face so he can get back to sleep but he gets so cranky I have to nurse him back to sleep.Also thru day his naps are 30 minutes max in crib or arms but in swing they can be longer.I’m so tired and have such bad headaches from taking what feels cat naps.And I also have toddler who sleeps with me and he is also going thru his own phase;screeching in the day like some fury or in his sleep so he wakes up baby.

I’m getting to tired honestly. 😭
