We just changed the older child in the baby's room! At this age they only have a nappy change about 3 times during the day so it's not as inconvenient as it sounds. At bath time, once again in the baby's room - we do bathtime for them all at the same time. I started TT-ing DS when DD1 was about 4 months old. DD1 is almost ready to be TTd now, so it's not like it was a situation that is going to last a long time. All lotions and potions remained with the change table, saved doubling up. Now DS is nearly 4 so we keep his moisturiser in his room because he can dress himself after we moisturise him to keep the eczema at bay, and the 2 girls use the same creams etc which are on the shelf of the change table.

Before DD1 was born I thought having the change table in the baby's room would be a massive PITA ie what happens if the baby is sleeping and DS needs to be changed? But surprisingly that just never seems to happen. When we are about to go out, both girls get a fresh nappy before getting in the car so easier to have it all in the one place. On the odd occasion the toddler might get changed on the floor...but the big thing for us is getting bath time for all 3 of them done at the same time, DH and I tag-team! Once again, easier to have all the gear in the one place.

Both times we moved the table before the baby was born so the older child was used to the new location before the new bub arrived. No problems.
