Hey Sophie - I agree with Winter, they do seem to 'fall' into a routine around 12 weeks - my DS started calling it a night at 630pm-ish about this age and would wake up about 7-8ish, and although he was still feeding 3-4 hourly at night at this point, he would go back to sleep within 15 mins after a sleepy feed. A tip that might help though is when Aiden is awake in the middle of the night eg from 12-4, keep things really low key - eg lights and noise low, avoid play, stimulation, too much eye contact etc and this may help him go back to sleep quicker - I used to stroke my little boys face and sing softly to him (and still do) to relax him.

Also, its never to early to start the bathtime/book/cuddle routine, although it might not work straight away, you'd be surprised how quickly they catch on.... as soon as we put DS into his grobag after a bath, gently massage and cuddle/story, he seemed to 'know' it was bed time and would snuggle in for sleepy cuddles and nod off for the night
