I have an 8+5 week old. I put her down for the night at around 8 or 9 pm. She'll usually sleep until about midnight which is when I'll feed her. Then she'll wake up every 2 hours for a feeding until about 7 or 8 am. She naps during the day for only 45 minutes or less. Just to note, she still feeds every 2- 2.5 hours during the day.  Any tips to get her to sleep longer stretches at night and take longer naps? Or is this normal?
