Currently I have 4 children 2.5 years and younger and one 4 year old who is able to run to the bathroom on her own and she loves the babies. That means 4 in diapers and nobody is toilet training yet, but there's going to be a lineup very shortly when I'm helping to train them all in the bathroom but I've been there done that before. Otherwise, I love the younger age group and having them grow and learn together.

I also get families to nudge their child to fit into our naptime before starting and children of that age should already be eating table food on their own so you aren't feeding them which saves a lot of time and stress at mealtimes.
