So my MIL is supposed to be planning my baby shower which is set to be on May 7th..nothing I mean nothing has been done yet😏 The theme will be very hungry caterpillar and I want to start at least making some kind of decorations or party favors..but idk where I should even begin..and I'm afraid she'll feel left out or as if I'm butting her out.Not the case at all..she kept telling me I was not to pay for any of it and that her and my SIL would take care of everything( my SIL somewhat hates me and I know it BTW) ugh ladies any ideas or help please! that's the only thing I've seen that I think I can make but where to get the caterpillar print outs??
