Hi hun!! Sorry you are having short naps!! They suck!
Ok, so your lo is 3 mo and she should be able to handle 1 hr 20 - 1hr 30 min A. Some of your lo's As are right, but some are too long. The first A is 1 hr 25 min long and that's giving you a long nap. She wakes up in the middle but goes back to sleep, so that means that 1 hr 25 min is a good A time for your lo. I would try to have 1 hr 25 min A for all her activity times and see if that helps.
Remember that after a short nap, your lo will not be able to handle her usual A time, so you will have to reduce it. Also, A is all the time bubs are awake, from the moment they open their eyes till they close them again. So, if she wakes up after a 50 min nap, then you count her A from the moment she woke up and put her back down after less A. So, may be, after a short nap (anything shorter than 1 hr), try 1 hr 10 min A and see what happens.
When having short naps, your EASY will look more like EASASEASAE, does this make sense?
So, for example if she wakes up at 12 pm from a 50 min nap, put her down again at 1.10 pm for another nap. Don't keep her up another EASY cycle until 2.30 pm b/c that will make her OT.
Hope this helps,
