My baby just turned 3 months old and he is crying a lot, he is hard to put to sleep as well as he fights it and cry a lot. We tried everything, changing his pampers on time, milk on time, give him time but he won't stop crying. He doesn't have temperature or any rash. He is really really getting hard to manage as we are unable to determine what is wrong. It is our first one but he wasn't like this before, as he would settle but not now, what would parents here recommend?
Not to sound obvious, but have you talked to the pediatrician? There could be a medical reason. Outside of the vague diagnosis of "colic," there could be gastrointestinal issues at play. But, excessive crying at 3 months isn't too odd. My oldest was like that even though she was 100% healthy. After about 6 months, she calmed down. Take him to the doctor, and if the doctor says he's okay, just be patient and watch for other odd symptoms.
It can be very frustrating not to know what the matter is. We had a similar experience with our daughter. She was tired but couldn't get to sleep. Took us a long time to figure that out, but when we tried taking a walk with her in a sling or holding her while gently hopping on one of those large rubber balls physiotherapists use, things started to get better.
Whatever it is, good luck!
We had the same sequence happen with our second child (not with the first).
After a few weeks of constant crying, we bought him a sleeping swing. Within 5 days he was falling asleep in 5 minutes. No more crying - for us either:-)
Incidentally, we never found out what was making him cry before - nor why he did not cry after.
Your mileage may vary. I have suggested a swing to four different friends who had the same problem as ours. It worked for three of them. Hopefully it will work for you?
The swing we bought had two mobiles and music. The mobiles (one B&W, one color) did not seem to make a difference, but the music was quite important. One tune worked better than the others.
"Colic" is a common problem with babies starting at 2 weeks-2 months, and almost always stops before 6 months. Our 2nd daughter had it (and yes, she was breast fed). It was like a 3-month nightmare. There are a number of theories about what cause it ( https://en.wikipedia.org/wiki/Baby_colic ), and a number of things you can try, e.g. leg presses (gently push the baby's knees up into the chest), colic drops, mother's diet or formula changes, etc. None of these seemed to do much for us.
We were careful to be very loving and comforting to her while we could, but when we just couldn't do it anymore we'd take her in and lay her gently in her crib, make sure she'd be comfortable, and then close the door and take a break for a few hours.
