MIL overbuying?

PLEASE tell me if I'm acting irrational. I might be. I've been married for 7 years. My MIL has a history of being overbearing, controlling, & boundary crossing. Despite this, we have managed to have a good relationship. She lives 5 minutes from me.

She has literally purchased thousands of dollars worth of baby items for this baby including: a video monitor, a changing table, a bathing tub, baby lounger, a baby carrier, countless baby clothing, a baby towels, swaddles, receiving blankets, diapers, bath wash, toys, books, etc.

For her home she has purchased a pack & play and travel system (stroller, car seat, base) & crib.

I'm mildly freaking out. Some of these items I would have loved to pick out myself- she gets hurt if I exchange things for a different style.

I'm nervous she feels like she spent so much that she's entitled to endless time with the baby. Is she crossing a boundary or should I be grateful that she's so involved!? it's okay to say I'm crazy.

thanks for your insight!!
