Credit Advise please.

Long story short, after baby was born I became a stay at home mom bc child care is way too expensive in the state I live in. We now just count with my husband’s income and we are living paycheck to paycheck. We have been using our credit cards more often then before and the interests on them are killing us. We just recently talked about consolidating all debts in one, but we do not know where to go about it nor what disadvantages there is for doing that. If any of you or anyone you know has done this before and have any type of info to share with us I would really appreciate it.
