What to do?!?

My daughter has been going to an all immersion Spanish daycare that we love! She has not been since April when Covid started and now I’m pregnant and due in April. This school will cost a small fortune to send two kids to but my main concern is her losing the Spanish. She is currently being babysat by someone who speaks Spanish but she tells me she doesn’t understand it anymore and doesn’t like it....she does understand it though.

My dilemma is that she will only be at this school for a little over a year after she goes back and then would go to kindergarten. They don’t have buses to bus kids to the school and the school will not bus them to this daycare so if we need before or after school care we couldn’t do it there. They have a Saturday Spanish class for kids but since my husband and I don’t speak Spanish I’m scared she will lose it and will have spent all this money to have her learn it just to lose it.

Differences:

Spanish school:

Already love it

Close to house

Baby would probably eventually go there even if chose other one now since so close to house (once older daughter goes to kindergarten)

Baby ratio is 4 babies to 1 teacher right now and only 4 babies total at school

Other daycare

8K cheaper a year for two kids

5 star (step up to quality) rated by state

Friends go here and love it

Closer to my work so only I could drop off and pick up

Kids would only go here for over a year until my first starts kindergarten

3 teachers for 10 babies but the teachers hours stagger so in early morning only one, middle of day 3 and later at evening 1

My husband doesn’t care what we do lol so I’m asking for other women’s opinions? Pay the extra in hopes my child learns and retains more Spanish or save the money and send them to another good daycare?
