DS is nearly 6 and Day 1 (Wed) went really well, he completed the set work, did 3 Zooms with school, we went to the park, did some fun activities etc, overall a really good, positive day.
Yesterday was absolutely awful and I saw behaviour that he has only ever demonstrated in the last month of the first lockdown. Tears and strops on/off all day. Rude, uncooperative with schoolwork etc. I’m so envious of those on another thread here in Primary listing all the schoolwork their Y1 kids appear to have happily completed, when mine is starting to battle me on it on Day 2 
I can’t believe I’ve got at least 3 months of homeschooling and it’s already like this on Day 2. He’s an only child and the social isolation is crippling- he’s seen no one since he finished school before Christmas (except other kids out and about), and is quite a sociable child so this is the root of the behaviour.
Anyone have any tips to cope behaviour-wise who also has an only child please?
