Down to 1 BF a day.... supply?

[Bearwantsmore]

DS is 14 months and now only has a single BF a day, at bedtime (abd occasionally during the night!) He has cow's milk in a sippy cup at other times. I'd love to continue the bedtime feed for as long as possible, but just wondered if it is possible? Will my supply dwindle with one one feed? I'd just like to be forewarned really if I am now nearing the end of BF!
Thanks.

Everyone's body is different. I got 2 year old DD down to one ten minute feed a day and my supply went. Cue DD shouting 'it's not working, broken!' :)

hmm i think it will just adjust tbh. dd is also 14m and just feeds before bed and sometimes v early morning. and i do hear her swallowing but not for long so maybe there is some. think its just for comfort now!
