Hello and welcome to BW forums
It sounds like you've made fabulous progress - Great!!
I would agree with you about BT being too late.
Take into account LO is only getting a 45 min CN (cat nap) prior to that last A time. This means LO is going to be more tired, not less, and likely to be able to do less A time or at the most a full A time (I see you are on around 2hr 5min - 2hr 40 for the other A times).
Some options:
- increase the length of nap 3 to a long nap. This means shorter A time before BT and BT stays at roughly 8pm which appears to give your LO a relatively good night of almost 11hrs.
- move the bath time routine MUCH earlier. A CN is literally only intended to get LO through the bath routine, so it is feed (if needed) bath, feed, bed.
If for example you brought bath time to 5.30pm or 5.45pm he is likely to be calmer during his ideal sleep window rather than crying through it.
- move bath time to a different time of day. If my memory is correct at this age some LOs find bath time too stimulating and it doesn't relax them for night sleep but gets them going and can't calm down. Trying bath time at a totally different time of day for a few days could help you see if this is the case. (you might have read the BW books more recently than me, it's been a while, I think Tracy said it's around 6 months this can happen but I can't be 100% sure).
- It's okay to feed as many times as LO needs prior to BT, you can cluster feed or LO can ask for cluster feeds. If you were previously feeding to sleep and feel this is a prop you could actually try just going back to feeding to sleep at BT and see if it makes a difference. Some people find that even if LO feeds to sleep at BT or night feeds they are still able to learn to self sooth at other times. If not then the prop can be gently removed, you can establish a clam BT routine with feeding and then tackle the F2S prop afterwards rather than the long period of crying and everyone getting frustrated.
A few ideas there, you may feel drawn to one more than the other. It's up to you what you try.
