Not sure how old is your baby but when they start nursery u can open tax free child account where u put money fir nursery and get top up from government .
You could set up a junior ISA to deposit the benefit into each month to gain tax free interest for them
Probably not much else. Without knowing what “good” is then it’s hard to say as “good” can be different to each person. Also depends whether it’s your first or second baby and if you are a single parent. Complete a benefit calculator online and that will tell you. If / when you return to work and have childcare costs you may be entitled to some help.
