In Scrum the team aims to complete the sprint goal by the end of the sprint. It shouldn't be necessary to estimate day-to-day deadlines since the delivery date is always the end of the sprint. I suggest you could stop trying to lead, stop estimating allow the team to self-manage.

A team of three people is quite small however, and one problem may be just that your sprints are too long and therefore too ambitious so they require too much planning and co-ordination with limited resources. I would expect that with a team of three a 5-day sprint is sufficient and 10-days is probably the maximum I would want to commit to. Planning two weeks ahead with a small and busy team is always going to be challenging. Your team could consider shortening the length of a sprint.
