It is totally normal. Kate does the same thing, she just turned three months. She usually settles quite well for naps during the day, either in her bassinet or the sling as we are on the go a lot, as I have a toddler as well. From about 7pm onwards, she is in a light sleep, nursing on and off until about 10pm, although for the last week or so, she is going down earlier into her bassinet, at about 8:30 or 9pm.
She will then sleep until 4am, quick nurse and back to sleep until morning. Sometimes she sleeps straight through.
I think a lot of babies like to nurse a little and often in the evenings. What I do is let her nurse on one side, do a lot of breast compressions to keep her going, then she usually drifts off for a while. If she wakes again to feed, I put her back on that same side, doing compressions, and then switch her to the other side after she actively stops nursing.
It sounds like you are doing great.
