Hi M.. Oh your poor little guy. It sounds like he's having some adjustment problems with recent family events. Only being two it's hard for his little mind to process the changes. I would suggest trying your best to get back into your routine, talk to your son, maybe spend a little extra cuddle time or doing something else that is calming to him just before bed time. Even though he's young he can still talk a little bit about what he's feeling and why. Have you tried talking to him about why he's feeling this way recently... hopefully before he starts getting upset? Maybe try to talk to him when he's in the early stages of his bed time routine. I'd gently bring up how he's had a hard time calming down for bed for the past few days, ask him if there is anything he needs for you to do. Maybe he's feeling a little insecure about the stability of his routine right now, that he may go to bed only to wake up to another change in the morning, etc and he probably just needs a little reassurance. You may try to talk about the next day, what's planned, etc so he knows what to expect and if he has fears of what the next day brings this could help to calm him. I'm sure whatever the cause, he'll return to himself soon.
