Hi Emma!! So, I agree with you...It does sound like some of your lo's naps are a bit UT, but then at the end of the day, he is going to bed OT b/c of the short naps. Does this make sense? And then, that causes NWs and EWs.
I think that I would try to add some A time first thing in the morning and see what happens. Then, if he takes a good am nap (anything longer than 1 hr), then repeat the same A before the pm nap.
About feeding schedules, I think that having bottles before solids is the right thing to do at this age. Milk is the main source of nutrition for bubs until they are 12 mo. Solids before 1 yo are just for fun!
So, if you have solids before milk, then your lo's milk intake will decrease, and that's not what we want right now. It will happen eventually, but when your lo is like 10-12 mo.
So tomorrow, I would try to add 10 min to those A times. Right now, your lo is doing 2.5 hrs A time.
6 am wake up
6.30 am bottle
7 am solids
A. 2.75 hrs
8.40 am - 10.40 am Nap 1
10.40 am bottle
11.40 am solids
1.20 pm - 3.20 pm Nap 2
3.20 pm bottle
4 pm solids
6 pm bottle and bedtime
If you think 6 pm is too early, then I would try to cut the pm nap shorter, and may be wake your lo at 2.40 pm, and then have a SHORT 30 min catnap at 4.15 pm and wake him up at 4.45 pm, and then go for a 7 pm bedtime. Personally, I prefered the early bedtime b/c the CN always gave us EWs.
Is there a way you can extend your los naps? have you tried shpat? Just in case your lo sleeps a short nap, you may try to shpat him back to sleep for the next couple of days, just to make sure he catches on some sleep and doesn't get OT.
Just remember that at 6 mo, it is very normal to have some sleep disruption. They are getting ready to drop the catnap, but can't handle the long A times yet. So it is very common to experience some EWs until they drop the CN!
Let us know how things go,
