Is my baby behind?

Delaney • Mom of a sweet little boy 👶🏼 baby #2 on the way 💙👨‍👩‍👦 🤰🏼

I feel like it’s my fault... my son hated tummy time and I told the doctor he said don’t worry about it he also skipped it too. Now my son can’t hold his head off the ground he has no back strength, he can’t roll over nor to his side. He doesn’t have the best head control. He can’t sit straight he also turns to the one side. When on his tummy he keeps his arms to the side and screams. My husband also thinks his motors skills are behind. He can’t told a toy with both hands and bring to his mouth. All he does is reaches for them on his play mat and kick his legs and moves his arms. I have so much going on with him and I am so nervous.
