Realistically it may be very difficult for your sister-in-law to get a TRV with no travel history especially if you don’t know how much savings she has. She will have to show that she can afford to travel and that it would not use a good percentage of your savings. You should have a plan B in case her TRV gets refused and you should apply as soon as possible because it may take a few months for the TRV to get processed. The biggest issue is really childcare for the 1-3 days you are in hospital since I assume your husband will go with you to the hospital at least until the baby is born and then all or part of the time until your get discharged. Your husband can help with household issues before and after work and on days he is not working. Would prepare some food in advance to freeze so that you have meals that can be prepared easily. Hopefully friends or community members will offer to bring your family a cooked meal or some edible treat. You can show your husband how to is things like use the washing machine, vacuum, etc. if he doesn’t know what to do. In general you may just have to accept that your house may not be as clean as it typically is, your children may only get very simple food or meals that you have frozen that you can reheat, etc. but that it doesn’t matter you’ll all survive. It sounds like your children are also of school age so they can also hopefully help you out, put simple things away, get you diapers and other items if they are in another room, throw out dirty diapers, etc.
