My little guy slept so well until the time change, even shortly after as well. But, for the last month, now that the birds are up and chirping before 5am, he’s decided that’s when he needs to get up too! Any tips on how to not have noise outside wake up my 19 month old? He’s got a blackout curtain. We have the house fan go on early, but it’s not loud enough to cover the cardinals.
