Hi,

It's hard to say if he is weaning or not. some children are happy to continue with just the one feed for a long time - others are less so. But it is pretty common at this age if he is only having one feed for them to continue on the natural progression of weaning that has been started. Have you tried putting him in his own bed and see what happens? If he goes to sleep easily, then perhaps how is the time to accept that he is weaning. You have done a great job.
Warm Regards
