2 year old + Daycare

Am I wrong for not putting my son in daycare? I’m just not ready and I don’t believe he’s ready either. But apparently my MIL doesn’t agree and thinks he will “learn quicker”. I’m due with my second soon and I believe I can handle 2 children. If I couldn’t I would have waited longer to have baby number 2. I’m not the only mom in the world to take care of 2 kids. Daycare workers take care of more than that so I don’t see the issue. What I want to know is if any moms with 1 or more children decided not to put their child in daycare. Did they turn out fine? I’m sure they did. I just wish my reasoning would be enough to get her off my back about it.
