Work from home UK

So I've just lots my job, due to being pregnant with my 2nd. It's not been said that's why but I told them last week i was pregnant and now all of a sudden I'm getting fired for something that has NEVER been mentioned before. I could bring my son with me to this job, it was perfect and I absolutely loved it, so did he. Obviously I can't be without a job with a 2 year old and baby on the way so im wondering of there's any wfh jobs I could do with children around. My son goes to nursery so I do have a bit of time without him around... but other than nursery i have absolutely no childcare so im in a sticky situation...
