Oh I hear you. My own 4.5 year old is home this week and tends to get the others riled up too! Too much energy! And naptime has been a struggle because my daughter hears her brother making sound and wants to get up too. Yesterday she did not nap and was a grump all evening....today I am still battling with her. Although in general, each day that my son is home gets a bit better than the last...he has calmed down a bit and the others have adjusted to him being here. Plus it was beautiful outside, so we spent most of the morning outside. Good luck! Only 2.5 more days of March break!
