I always try to work smarter, not harder! I have 4 kids. The first ones (twins) were almost 2 when I got pregnant with the 3rd and then that child was 18 months when I got pregnant with the 4th. And from 3-8 months pregnant I had all 3 of them home with me all day every day. As you can imagine, it was...challenging. I've learned to work smarter, not harder. Off the top of my head I can think of a few things that made/make my life slightly easier.
Firstly, contain the child. Gate across the door of the room that you're both in or just shut the door if they can't open it yet. Stops them running about the entire house like a nutcase.
If you have stairs and need to go up with them and they're capable then do not carry them unless they're going batshit about it. They can climb up while you walk behind them.
If they want up for a cuddle then fine. You sit down and let them climb up onto you with a little bit of assistance rather than hauling them up when you're standing.
Distraction, distraction, distraction. You know what your child likes and what works to keep them happy. Use that to your advantage. Make your own day easier. Giving them more treats than usual to avoid a tantrum or shocker a bit of screen time temporarily won't damage them forever.
Pick "clean" meals rather than messy ones to reduce clean up for both them and the floor (but also your husband can take care of the clean up when he's there) And by clean food I don't necessarily mean healthy because it's not the time for that right now😂. Also if you don't already use them then invest in a few Bibado type bibs or similar. Honestly, game changer. Reduce the need for a nightly bath.
No clothes with poppers or buttons. Vests possibly fine. If they're wriggling too much to do them up then ah well, just tuck the ends of the vest in. Pick 2 piece pyjamas over sleepsuits. Too many limbs flailing around. Pull ups over nappies because they're much easier to put on a wriggly child.
As others have said, your husband (when he's around because there really isn't anything wrong with a one off Christmas night out) should be picking up the slack in terms of lifting, running around and housework etc. Getting kids into car seats too. Why is that like an Olympic sport at the best of times??
Different people have different pregnancies. Yay for the people who were fit as fiddles during theirs. Personally, I was somewhere in between. But I still didn't put myself out if I absolutely didn't have to!
Edited to add don't take them to soft play! I've never found it tires my kids out. It seems to rile them up instead. Then again, mine have all been shit at napping. 1 hour max and the 3rd child gave up napping completely at 18 months. That was nice... Anyway, don't be running around a soft play after them. Find somewhere you can sit down. Ideally where other people will help 🤣
