Hi Sarah, welcome to the boards!
So it looks like your dd is napping for 1.25 hours, .25 hours, 1.5 hours, and .5 hours--is that correct? That's a bit lower than the recommended 4 - 4.5 hours for this age.
You're correct that poor daytime naps can affect nighttime sleep. In addition to the amount of daytime sleep, the timing of naps is important. Babies need to sleep at certain times. At 4 months, your dd's natural biorhythms are developing a pattern which calls for a midmorning nap about 2 hours after wake-up of 1.5 - 2 hours, another early afternoon nap around 1 p.m. of 1.5 - 2 hours, and an early evening catnap. Wacky nap schedules can throw off your dd's natural rhythms and lead to restless nighttime sleep.
It's normal for babies to need two night feeds at this age. Four months is a prime time for a growth spurt too. Do you feed at midnight when she wakes? My dd wakes at midnight sometimes but will usually resettle without a feed.
