22 month old started nursery this wk now not sleeping

[Bedsheets4knickers]

She's always been clingy , she had 2 settling in sessions the week prior , 2 3hr mornings this wk. now she's waking every 3hrs crying. Could this be nursey causing the disruption. Or maybe 2yr sleep regression. I'm feeling mothers guilt !!

Yes cd definitely be nursery. DD took about 2 weeks to settle down. I found lying next to the cot while she calmed down helped.
