can we claim anything for childcare when jobcentre send my husband on a 3 week course

i work part time, usually 2-3 days per week, we dont have anyone for childcare other than the childminder we previously used.
money is tight as hubby got made redundant in december, the jobcentre said if he doesnt attend these courses then his benefit will get stopped.
money is very tight and we just cant afford to pull out money left right and centre :(
longshot but would child tax pay anything towards it ??
thanks
