Regardless of when my LO has feed during the day, I always feed her at 8:00pm, bath her (every second day), cuddle with her and read a book, and then she falls asleep and I put her down. I think consistency really helps, however, every child is different. So what works for me, may not work for you necessarily. I would try the last feeding at 7:30 each night and see how it goes from there.
do you wake her if she is napping to start the routine? If she has been up already for awhile do you keep her up and risk her being overtired?
I am just curious because I would like to start a routine for my LO but she feeds/naps at different times every day and if I suggested waking her up in the evening my husband would probably lock me out of her room.
