Whats your opinion on this?

i have two children one is 6 and a half will be 7 at the end of june and the other is 3 and a half weeks. my 6 and a half year old has a touch rugby game on friday after school its being played at the park aroud the corner from our house. he will quite often go round there to play on his own as we live in a small town and its only round the corner he has to cross one road though its not a busy road its not very often there are any cars driving by. however with touch starting on friday there probly will be a few cars he has good road sense. what would the other parents think of me if i allowed him to go along on his own as my 3 week old baby isnt in a routine yet and i dont want to feed in public??? or what if i just put baby in pram and walked him there and stayed till i needed to feed him? i do want to watch my son play but would feel more comfortable if i dont have to feed baby there. would i be judged meanly by the other parents if i dont go?
