My DS (16 months) has always been a very sociable little soul, has been going to nursery since Sept and usually runs in without a backward glance at me, dives straight into breakfast etc. Last Monday he was fine. The day after, as soon as I put him in his chair for brekkie, he started crying and holding his arms up to me. Ditto every day since. I have called them and he's fine the rest of the day. Been a bit clingy at home too. Is this separation anxiety do we think or making me feel guilty (is he old enough to do this?) I'm finding it so stressful as he's never normally like this
