It's been raining here all day too. I'd like to see some sunshine but we do need the rain.
For some activities you can do with your toddler.
Read books to your toddler and try and get your toddler to learn to read along with you.
Do puzzles, puzzles are always fun.
Go on youtube and find some shows your toddler likes and you can keep them entertained for hours.
Get out some legos if you have some, legos are always fun.
