Gem, offer babysitting - LL11 Coedpoeth

I’m a single mum with Autism and want to come off benefits and support my daughter financially so I started a personal training course when I was pregnant and now need to start the physical side of training so would need to get the train to Warrington one weekend out or every 4-6 weekends I would be home on the Saturday evening then need to go back on the Sunday so was wondering about Costs as universal credit won’t help as I’m not currently in work they say I should look after my daughter myself and don’t seem to understand this is so I can try and get back into workz
