Hi! Sorry for the troubles! 4mths is a tricky time!
What she is going through sounds very normal. Around 4mths their sleep changes! It is developmental. They also begin to make sleep associations. So however they are falling to sleep, they expect it when they wake and go through their sleep cycles. During this time, their sleep changes to more like "adult" sleep. If they do not know how to sleep independently, they will wake and need help. Mine did the same thing... Used to sleep so well then around 4mths it changed and we needed to find new ways. Fun. Haha! He's now 22 weeks and we survived

....still with some bumps though along the way haha
Now, I can try to help out by suggesting a few things with her EASY. I do see her naps she wakes after 45 mins... Again, could be developmental OR she may need a push in her A time. She might not be tired enough. Here is a link worth looking into about typical A times:
Average A times- BOOKMARK ME! If you notice.. Your reaching closer to 5 mths so by now I would try increasing from 2hrs to about 2.10/2.15 (whatever best she can handle) ...and slowly increase over the course of a few days.
Now is also a good time to identify sleep associations to try and help her learn to sleep independently soon. It helps loads. Gradually and gently you can help her as these next weeks pass by.
One other thing to consider, at this time there is a growth spurt... So try a feed! I know around 4mths my little one began to wake around 12-1 and then 4-5 also... It's pretty common to see! So hope that helps ease your mind and know it will pass.
Hope this helps! Sorry it took a bit to get a response to your post!
