I supply bibs. Parents are asked to supply a sippy cup but I do have some here if I do not like the kind sent (and if I see the child has trouble with the one mom supplies). I supply bug spray and sunscreen but charge an additional $10 fee every April to cover the cost of purchasing it. I have smocks here but use them too often as I am not a big fan of overly messy art! Lol. I also don't do art with kids under 2 unless it's handprint stuff for special occasions. I have a bin here for each child to keep extra clothing in. As far as hats go I send out a newsletter usually monthly detailing things I want - for hats I ask for wide brim hats with Velcro ties under the chin.
