My boys are a year and a half apart about and I feel like it's a good age gap. The older one is still a little... Well, no, he's three. He's needy, but he can help a little bit and he is starting to be more independent. And I've noticed for the little one, he is developing a lot faster. Like he's talking so much and he's just doing so much because he has big brothers. So I think it's a good age gap.
