I have an interview at the Early Headstart I sub at for a full time position. I also have a 2 yr old and 4 month old that I need childcare for. I attempted to get them in this past Summer but no slots where a available and I'll try again this Summer but still no guarantees. I'm worried about it, both being qualified for the job and if I do get the job, what will I do with my kids? My mom helps when she can, but she has doc appointments sometimes and my husband helps his mom a lot. Idk there aren't too many daycares here that I feel are qualified. I mean education based, that actually have a curriculum and will teach them.
