Hi all,
Title makes it seem a bit run-of-the-mill but I'd like some opinions.
I am a single dad to a 22m/o LB, who is my world. I work full time, and thus, LB goes to a nursery Mon-Fri. He has gone since he was very small, ~6 months old, and has loved every minute as he's grown. He has lots of friends, is a good sharer/plays well (for a toddler, mind you), and loves the ladies that run the nursery. He is a very happy little guy, easily pleased, full of beans, cheeky, chatty etc etc.
However, in the past week, he has suddenly grown VERY clingy. He screams and cries and refuses to leave me in the mornings, and will not calm down. I was actually called to pick him up today as he was so upset. This has NEVER happened before, and I'm so confused/worried as to why everything has changed. Nursery workers tell me nothing's happened, the parent workers that do shifts at the nursery say the same, nothing has happened at home. Nothing has changed in his life, in short.
I'm just looking to see if anyone has any advice for dealing with it? I obviously left work today, and have got tomorrow off, so I can spend some time with him. He's pretty much been glued to me all day, but has been his usual self apart from that. Currently wolfing down his dinner, so I don't think he's sick... 
Yeah. Any advice appreciated, TIA!
