DS, age 3, has just started nursery, having been out for 18 months due to a mixture of Covid and mat leave. When I picked him up, he said he'd missed me, he'd been looking for me, he'd been crying and hadn't I heard him 
DS is quite reserved and not very sociable. We go to lots of toddler groups and see other children his age every week, but he often plays alone, so I knew he would struggle. We've also only spent a few hours apart at a time since Covid hit. Financially, I have to work, so he has to go in 2 days a week.
DS cried and cried at drop off this morning. It's only his second day. Please tell me it gets better!
