We always had "bed time hour" which started 1 hr before night sleep started.
At 4 months my DS still hated baths so I didn't do them daily and not near BT which would have upset him too much. But at around 5-6 months he did like baths and our routine was:
20 min gentle children's TV programme, very low key and calm one not a noisy exciting one. I used this time to prepare milk and meds, run the bath and get his pjs and night nappy ready.
20 min teeth brushing and bath, get dressed
20 min feed (say 10 min), cuddle and a song, into bed, leave (before the hour was up).
Lots of people like to do bed time stories/reading but all my DS wanted to do was get to bed to be honest. Books were too stimulating for him and we didn't do books at BT until he was about 5 years old.
