Any signs of Reflux?
Are you BF or FF? Either way it looks as if your LO is a snacker, I am afraid. It sounds like you already know that, though. I can see two ways to go about it, one is to gradually reduce the middle of the A and the end of the A (right before S) feed. You can do it by shortening the feed by a minute every 3 days if you are BF or reduce the bottle by an oz every 3 days if you are FF. For the feed after WU you keep on offering a full feed and if she empties it then you can start and increase it because she will shift her calories to that one feed instead of three (at each A). The other option is to go "cold turkey" with those two feeds and leave just the one after WU. There will be some crying and you will have a day that she is more hungry and unsettled but it should sort itself out as she will learn that she needs to take more at this one feed.
If you are BF it's very important that you do transition to have more gaps between the feeds because if she is snacking she is not getting enough of the hidden milk.
Also, if you are BF, don't expect that she will space her feeds to 4h, most BF babies don't get to that until around 6m old. The right way to go about it is to get her on a better A (I'll get to that in a sec), get better naps and then feed at WU.
Right now her A time seems rather short for her age. If you looked at the links Kara gave you, you can see that most babies her age are doing 2h A time and some even more than that. Her first nap seems UT to me, as well as the second one and perhaps by then she is OT because she didn't get any restorative sleep in the first part of the day. IIWY I would be working on increasing her A time to be more around 2h throughout the day and perhaps she will need even more than that. It's better to do it gradually to prevent her from getting OT and it also takes LOs a few days till they get used to a new A time. So you increase the A by 10-15min every 3-4 days. If after 4 days you still get UT naps (between 45min and 1:20h) then you increase the A again. If after 4 days you are getting OT naps (30-35min) then it could be that the jump was too big for her and she would need 5-10min increases or that she just needs more time to get used to it, then I'd stick to it for a few more days.
What do you think?
