Hi. I need some advice. We are leaving for Disney World in July. My baby will be 5 months old and I will also have a 4 ½ year old. Im worried about the stroller situation and my 5 month old daughter in the sun and heat. I was thinking of taking a double umbrella stroller because we stay at the Boardwalk and we do a lot of walking from EPCOT to the Studios and it will be too much for him. My son was 9 months old when we took him so we put sunscreen on him and he was able to sit up in the stroller. I honestly dont remember what its like having a 5 month old! Can she sit in an umbrella stroller by then?? What about sunscreen?? The umbrella stroller isnt as protective as her sitting in her infant car seat, however I thought she would like to see things as we walk and the carrier would be too hot. This is our first trip with two kids so I want to pack as light as possible! Any suggestions???!!?!
