That sounds sooo much like Nina, would only fall asleep with movement!!

Give the EBM a go and see if that works, also do you think he may be teething? I know he's only young, but nina started at 8 weeks. Another thing is, is he ready for bed for the night do you think? That was another thing we looked at. We would start the bedtime routine at around 6.30, but then realised that was too late, and therefore nina was getting over-tired, so now we start between 5.30-6pm.
