Cathy, I don't claim to speak Spanish, but all of my kids did as toddlers. (For the oldest, it was because our day care provider spoke only Spanish to the kids. For the rest, it's because my husband has become fluent in Spanish and speaks to the young kids primarily in Spanish.)
Anyway, you probably already know these words, but these are the ones I find most useful with my kids:
leche=milk
pan=bread
come (CO may)=eat
agua=water
jugo (HU go)=juice
libro=book
jugete (hu GE tay)=toy
biberon=bottle (my son shortens this to bibi [beebee])
mas=more
no mas=no more
You might also find YouTube helpful for any future nebulizer treatments. My toddler loves Spanish-language kids' music videos and short cartoons. Some favorites are "La Vaca Lola," "Cucu de la Rana," and the Spanish versions of Poco Yo.
Apologies in advance if I'm telling you what you already know. Blessings to you and the children.
