Youngest son started reception last September (he's a July baby, so very young for his year) and settled in exceptionally well and has made lots of lovely friends. He also has lovely teachers and is doing very well. However, since half term he has been breaking down in the mornings going into school. Just clinging onto my legs and quietly breaking down. One of the teachers has to come peel him off me every morning and it's become a horrid way to start the day. He does this to DH too.
He is absolutely fine getting up for school, getting ready for school and walking to school but he just breaks down at the last minute. We've asked him why and he says: "I just love home so much and I miss Mummy/Daddy too much. The day at school is long." 
I'm pretty certain there's nothing going on at school. So how do we manage to break this pattern? It's a horrid way to part company in the morning. I leave him feeling totally rotten and walk to school feeling a bit tense in anticipation. But it feels all wrong to teach him to suppress his feelings. Ugh.
Please, wise Mumsnetters, how do I break this cycle?
