Baby sleeping pattern. Nap after bath.

My baby girl is 2 months old and she was sleeping fine in 1st month but from 2nd month she is taking short naps in the evening of 5 mins only. She sleeps in night at 12 or 1am till morning 6-7am. Then 8.30-11am and then she takes bath and sleeps for 1hr only from 1-2pm after that she doesn't sleep till 10.30 pm except 3-4 naps of 5 min and 1 nap of 30 min. After 10.30pm also she takes one more 30 min nap and wakes up and stays cranky till 12.30 or 1am then she takes feed again and goes for long night sleep. She takes proper feeding , I give her colicad sometimes, I tried swaddling , white noise but nothing worked. I don't want to use pacifier or milk bottles. Please advice what can I do to take her long nap after bath.
