At current time, all 3 children are in the same day care facility. DD1 has not been working many 5 day work weeks (M - F) since her husband went into training, as she earns four weeks of leave time/year and also has sick leave. She usually works 9 longer days and gets a day off out of the M - F (so the extra day off every other week). It works because daycare is super close to her work site and she drops them off as soon as she can and picks them up as late as she can. Tuesday she took a day off to do a big grocery shopping, and rest of day at home to get some things done and also get a short nap. She is 28 and has more energy than someone older, even with her pregnancy.
If she does take the 12 weeks maternity leave, and husband is still away (he will be away either in training or at his Army assignment), that is where she will need me to be a FT live in assist. The older one (or two) will probably go to Catholic school (K4, and kindergarten for the 5 YO) - or I will keep the 4 YO, and I will do the drop off and pick up for the school. DD1 and the younger two will follow the current routine with mom.
As soon as her 12 week work time is up after the maternity leave, then DD1 and all four kids will be packed up and move to off base housing with her husband at his Army assignment.
SIL seems to have a bright career with cyber security, but will take him some time after his Army commitment to get up to what she makes now. It depends where he works as to cost of living. We have a lot of opportunities where we live, and if the time comes, we can move and let them use our house (housing costs are really going up here, and we have 4 BR/3 BA home).
DD1 and SIL have desired for her to be SAHM, which may only be financially feasible for a short while – but hopefully after he has completed his Army duty, she can regroup. She is very good at budgeting, but how lean of living they can do, who knows. Because she has over 5 years in with the VA hospital, she can pick up some kind of work with them as a RN - and she will keep pay level and pay grade for a time, but IDK if that is only with FT work. I think she is getting herself boxed in to being SAHM, because the whole child care and raising the kids, she cannot try and work some hours and then be exhausted and not really be satisfied with the arrangement.
I do think she will ‘rethink’ some of the ideas she has (like homeschooling) - SIL was home schooled but there was only 2 of them. I was an older mom, and my DH is same age as me (we were 38 and 40 the years our two DDs were born) and DD1 will be 29 next Feb. I focused on family time and time with DDs before school and from school end to their bedtime - they were in a lot of music and sports extra curricular. They typically had a snack and or a meal soon after getting home, and towards the end of the evening finishing up homework. When my DH had to travel internationally and nationally a lot, I had to become SAHM when DDs were 3 and 5, as we have no family here and the kids needed to be raised properly with proper love/attention/oversight. School/activities/home was very busy. DD1 said she wants to raise her kids like she was raised, but SIL’s ideas have influenced quite a lot of her ideas. I just don’t want to see her become an old woman way before her time!
