My LO is 13weeks and since 5 weeks old we have encouraged him to stay awake in the evening so to sleep longer over night. We stimulate him from around 7pm by playing,singing, undressing him if necessary, bathing him then feeding him before nursing to sleep. This has worked successfully in that he sleeps through from around 10/10.30pm to 8/8.30am. He has recently been getting very tired in the evening though and although we are persisting in stimulating him, bathing him etc to keep him awake I wonder if he wants to go to bed earlier. He did go to sleep earlier the other night and woke up at 4.30am for a feed. Do/did you encourage a routine like this or would you let them sleep in the evening regardless?
