Hi and welcome to the BW boards!
It seems that you are still feeding every 3 hours during the day. Is she taking a good feed at that time? Do you think she could go longer between feeds? At her age she should be working towards a 4 hour routine, meaning that she would eat every 4 hours. Not all babies are ready for this right at 4 months, however.
Have you tried to extend her naps? It seems she always sleeps about 50 minutes.
She might be able to handle 2 hours of awake time between naps and if she can she might be able to do a four hour routine, however I notice that at one point in your day she had more than two hours. That is a long A time for a baby her age. Overtiredness can cause short naps and night wakings. It is important to keep her rested during the day.
A good 4 hour routine might look like this.
7:00 wake and eat
9:00 nap (2 hours)
11:00 wake and eat
1:00 nap (2 hours)
3:00 wake and eat
5:00 nap (45 min)
5:45 eat
7:00 eat and bedtime routine asleep by 7:30
You might find that she isn't ready for that A time or that she can't quite go that long between feeds. If so you can work towards a 3.5 hour routine.
I just noticed that I have assumed that she is about 4 months...
How old is she?
