My son said I love you Unprompted

My 4 year old son has only been really talking for 10 months and until a few weeks ago it was all request/response. But we’ve started getting unprompted speech and tonight after bath I was drying him off and he said “I love you.”

There was such a large part of me that thought this would never come. A lot of days are really rough and I’m so scared for what the future holds but there’s also moments like this that just makes it all worth it
