Thank you for your answer!
The reasoning behind cool bath is that it's supposed to stimulate active movements during bathing, which makes him physically tired, which in turn shold make him sleep better.
Here's our EASY routine (yesterday):
EW 6-00 (not always, but during last few days we have it), sleeps for 20-30 minutes
WU 6-45
E 8-00 BF, 9-00 solids
A
S 10-00-12-00 (I often wake him up)
E 12-00 BF, 13-00 solids
A
S 15-15-16-00 (sometimes I wake him up, because when he sleeps past 16-15, he gets very cranky and active in the evening)
E 16-00
A
E 18-00
A 18-20 bath
S 19-30 (I finished BF at 19-00, but he didn't sleep for 30 minutes after it. He looked around in darkness an my hands, rolled his head very fast and lisped "dadadada", tweaked his legs and arms. I didn't know what to do so I just held him untill he calmed down and then put him in his cot.)

Our last activity looks like this: after BF at 16-00 we go for a walk in a stroller for 40 minutes to an hour. By the end of the walk he ofter gets cranky. When we get back home he has some more activity (he usually has better mood at home) while I'm preparing his solids. After dinner we go to the bedroom, where I close the curtains, turn on the night light and we prepare for a bath for a few minutes. Then we have a bath (I dim the lights in the bathroom and try not to stimulate him, but he still wants to jump and shout). Me and my husband try to calm him down, but usually he gets tired after 10 minutes and starts crying. I used to bathe him in cool water (around 30 C), but lately I've raised the temperature to 35 C hoping it would make him calmer. Then we carry him around in the bedroom to calm him down, but it doesn't always work. He also gets upset when we dress him in him pyjamas for the night. Only during the last BF he calms down completely and drifts away into sleep. I tried less activity time before sleep, but then he's not sleepy at all and it's extra hard to calm him down.
Another thing that worries me is that he started having extra long naps in the morning, because it leaves less time for the second nap (he often has catnaps in the afternoon). I've noticed that it was easier for him to have his 2nd nap finished by 15-30 so to be asleep by 19-00. He felt asleep faster and more peacefully. But I'm afraid it's not good to wake him at 11-00/30 from his 1st nap (I also feel strange waking him at 12-00 after 2 hours of sleeping).
Sorry for long story! I'll appreciate any suggestions!
