Is my strategy good?

Is my strategy good? I started investing two months ago. I contribute a set amount monthly, which I plan to increase as my income grows. I'm based in Europe and use IBKR. Since I'm in Europe, I invest in euros each month I buy 80% into a large-cap ETF (WEBN, the UCITS equivalent of VT) and 20% into a small-cap ETF (WSML, roughly equivalent to VSS). My plan is a typical Boglehead approach: invest monthly and let it grow. But I'm also considering adding government bonds via a bond ETF. Should I? Is this strategy sound, or should I change anything?
