Initially only you need to stop this,pacifiers are not at all good...

Try to distract the habit,don't show pacifier to him, he starts to cry or gets irritated...show some toys and change his habit ...

Hi sleeping pattern differs in every baby and will vary till age of six months after that it will become constant gradually

It can b due to some stress , baby went thru in daytime , which remained in her mind & while sleeping it made her wake up & cry.First try to understand what she remembered while sleeping.Ask baby about it

Hi is your baby having blocked nose?

Aap raat mai two times use jaga ke toilet karwa ke phir sulaiye.
It will take some months aadat dalne k liye

Make a proper routine. Stick him to the bed turn off the lights, tell him stories. Keep him active during the day. Daytime nap should not be more than 2 hour. Play With him in evening so that he could jump and get tired which will help him to sleep at night easily. It takes me half an hour to make my baby sleep 😴😂. He also do lots of dramas but I stick him to my lap and narrate a story and makes him sleep.

Mentioned that sleeping time at day time is more,that's the reason...

So first avoid more day time sleep, gradually you can sleep at night...
