Same as my baby when my dear daughter is 1-2mos old. Maybe baby has tummy ache? Or overtired? Sometimes overtired babies become difficult to put to sleep at night. Can make sure if baby gets enough nap time during the day. I swaddle my baby and then rock her to sleep. Sometimes while rocking her i also give her pacifier. Then sing a song or the "shhhhh" sound. Try reading "the happiest baby on the block" by harvey karp. The 5s works for my dear daughter.
2. Swinging or rocking
3. Shushing (shhhhhh) sound
4. Side position/stomach (dear daughter doesnt like this)
Give it a try. Good luck!
