You lucky girl, your parents down the road. I'm sure they'd love to help you out and babysit. Mine are thousands of miles away. There's no real reason why they shouldn't bond and play with your dc, no? So go for it!!
I'm at home at the mom, 12 wks old babe and I have enlisted the help of a cleaner to see me through the week. I prepare all food in the morning when baby is asleep, you could have your 2 yr old watch or cheat and buy ready made, dress up as yours, no one's gonna die from it for 2-3 years
I find even without make-up the following things help to look groomed and sexy (not sexy as in that red-blue tanga thing, but desirable): have your eyebrows done once (threading) and then re-do them yourself every few days, whatever necessary. No spots, etc should be seen, cover up, get a facial and benzoid cream 5%. Shower & do your hair, don't go for high maintenance colours and opt for an easy cut that won't take much time to maintain. Make sure your nails are glossy, feet and hands smooth. Buy a good scrub and lather up, put oil on your cuticles and a facemask on while you're cooking, showering, etc. You get the idea, rather than one big almighty overhaul, do bits every day, everyone has 5-10mins.
When the kids are with your parents make a nice dinner/lunch and just be you. He married you once, right? Don't get all worried and eaten up by it, you are lovely and beautiful as you are. Do the beauty stuff to make you feel better & look groomed, then work on letting your parents babysit. Use that free time to reconnect.
Mundane, what is mundane?? Jeez, tell him to get a grip, he's not 17 where the biggest excitement is going round a friend's and getting blind drunk. He's a man with responsibilities. To get him out of that state do plan something, 1 thing every week, with or without the kids to give you something to make new memories together, to talk about new stuff.
