Cup of tea and a biscuit, the holy grail of toddler mums!
I’m with you OP, DS is 2 and 90mph being cooped up and I don’t have the excuse of being pregnant.
Mine spends ages playing with his Aquadoodle mat (Amazon and Argos sell it) you put water in a pen, scribble and colours show up and they disappear as it dries. DS shouts out items and I have to draw them. We bought another set of the pens so we can all play together like a backwards game of Pictionary!
Balloons are the best at wearing him out, blow up a few and bat them around the room and he chases them, uses them to whack things with, great fun! DS and DH can play catch with them while you have a cuppa and keep score.
Asda were selling gingerbread man decorating kits. I haven’t attempted ours yet but should be fun and at least I can eat the leftover mess!
Hot chocolate station? Maybe more a warm chocolate milk station but he can add marshmallows, sprinkle some cocoa on top etc.
If you have an Alexa the CBeebies skill has games, songs and interactive bits for kids. DS loves the Hey Duggee game where you create a song. If you ask her to play a specific animal noise she can keep playing random ones which is fun and informative.
Cardboard box colouring. Biggest box you have and make a fort. Or use the little boxes to create things for his toys. I drew inside a small box to make a very lovely house for Spider-Man the other day!
