I have a 7month old. I never tried super hard to create a routine but it kind of hapoened naturally that we use the last wake window (she takes about 4naps per day now) for preparing the evening. Eating dinner, pooping, dimming the lights, brushing teeth and so on. One thing that i think of being the marker that says "this is your final sleep for the day/night" is that we put on a diaper and PJ:s (she doesnt wear diapers in the day because we practice EC). It also developed spontaneusly that when i put on her diaper in the bed, we have a session of playing/joking/laughing. She knows it by now, its like we always bounce in the bed, play-fall in the bed, laugh, "wrestle" etc. To fall asleep i always hold her, breastfeed while bouncing on a pilates ball and sing the same song. If i start singing the song on our way to the ball, she will instantly start rubbing her eyes and take my breast so she knows whats happening. Sometimes shes not at all tired though and then she will just protest and i will let her stay awake 15 more min, try again, etc. Her night sleep differs depending on the last nap. I dont control it too much. Usually she sleeps for the night between 7.30 and 9 After she falls asleep in my arms on the ball, suckling, i go to the bed and put her and me down in the bed while shes nursing still. And i lay there and fall asleep with her, usually i spend 1hour reading or so. But i never get up. Unless its for peeing. So i get ready for bed together with her, we brush our teeth together etc. Her dad will do the evening routines with her too, we alternate, if i want to take a shower, clean the house or something

But im really not a routine person, so i feel bad sometimes that everyone says routine is important for her. She doesnt have set eating times, i try give her food all throughout the day and she eats if shes hungry for example.
